  Abstract
  In this work, we have studied the optical properties of L-arginine potassium iodide (LAPI) that has been synthesized by slow evaporation solution growth method using water as solvent. The phase purity of as grown crystal was verified by single crystal and powder X-ray diffraction methods. This paper is focused on the optical properties of as grown LAPI crystal. For that we have studied the optical transparency and dielectric nature of the grown crystals by UV–vis–NIR spectrum. Second harmonic generation (SHG) efficiency of the LAPI crystal was investiagted by Kurtz-Perry technique using Q-switched Nd: YAG laser. We have also studied the dielectric constant and dielectric loss of LAPN crystal as a function of frequency and the obtained results are discussed.

The FT-IR and FT-Raman spectra of the title compound have been recorded in the region 4000−400 cm-1 and 3500−100 cm-1 respectively. The molecular structures, vibrational wavenumbers, infrared intensities and Raman activities were calculated using DFT (B3LYP) method with 6-31+G (d) basis set.

  Abstract
  A novel semiorganic NLO material viz., L-arginine potassium iodide (LAPI) has been synthesized by slow evaporation technique. The crystal structure and lattice parameters of the grown LAPI crystals have been determined using single crystal X-ray diffraction and powder X-ray diffraction techniques. Single crystal X-ray diffraction study shows that the material crystallizes in monoclinic structure with the non-centrosymmetric space group P21. The FTIR spectrum was used to identify the various functional groups and modes of vibrations present in LAPI crystal. The mechanical strength of the crystal is estimated by Vicker’s hardness test and the obtained results are discussed.

  Abstract
  The ultrasonic velocity, density and viscosity in mixtures of Cetyl Pyridinium Chloride (CPC) with Cellulose derivatives (Methyl Cellulose (MC), Ethyl Cellulose (EC) and Hydroxyl Propyl Methyl Cellulose (HPMC)) in different concentration ranges are measured at different temperatures 303, 313 and 323K in order to find out the Critical Micelle Concentration (CMC) of Surfactant / Cellulose interaction. From the experimental data, other related acoustical parameters such as adiabatic compressibility (β), intermolecular free length (Lf), internal pressure (i), Rao’s constant (Ra), absorption coefficient (α/f2), free volume (Vf), cohesive energy (CE), relaxation time (), acoustical impedance (Za) and solvation number (Sn) have been evaluated. All these parameters have utilized to study of various molecular interactions takes place in the solutions of CPC – Cellulose derivatives (MC, EC and HPMC). The FTIR and UV analysis also used to characterize these samples. The results are discussed in molecular interactions that prevail by hydrogen bonding.

  Abstract
  Mn doped CdO thin films were deposited by perfume atomizer spray pyrolysis method on glass substrate by varying substrate temperature (T=2000 C, 2250 C, 2500 C, 2750 C, 3000 C). The X – ray diffraction (XRD) analysis show that the prepared cadmium oxide thin films belongs to cubic structure with preferential orientation along with (111) direction. The thicknesses of the films were determined by Stylus profiler. The average optical transmittance of the CdO films in the range of 300 – 800 nm, is about 58%. Estimated band gap energy (Eg) is 2.65 eV and 2.5 eV. Photoluminescence (PL) spectra showed a strong emission peak around 523 nm. A systematic study on the influence of the substrate temperatures on the optical, electrical and structural properties of Mn doped CdO thin films deposited by perfume atomizer spray have been reported.

  Abstract
  Semiorganic nonlinear optical material L-Lysine with zinc acetate was synthesized at room temperature in single crystal was grown by slow evaporation technique. The grown crystal was confirmed by Powder X-ray diffraction analysis and the major peaks were indexed. The single x-ray diffraction analysis reveals that the crystal belongs to monoclinic system. FTIR vibrational spectral study was used to identify the functional groups present in the grown crystal. The optical transparency of the grown crystal material was investigated by UV-Visible Spectrum. The Vickers Microhardness studies reveal the mechanical strength of the grown crystal. The L-Lysine zinc acetate was studied to be thermal stability of the grown crystal TGA and DSC. The SHG (Second harmonic generation) of the crystal was tested by Kurtz-Perry Powder method.

  Abstract
  Herein we have present the preparation of Nd doped ZnS thin films on glass substrate by simple nebulizer spray pyrolysis (NSP) method at 450 0C. XRD, SEM, and UV-Vis Spectrometer were used to analyze the Structural, morphological, and optical behavior of the prepared samples. Nature of polycrystalline hexagonal structure with no secondary phases was confirmed by X-ray analysis. Extra particle creation on the surface of the Nd doped thin film was observed in high magnified SEM images. Room temperature PL studies depicts that the luminance behavior of the parent sample was enormously changed during the Nd element interstitial with ZnS lattice. Optical band gap value varies from 3.51 eV to 3.58 eV for 3% Nd doped ZnS film ascribed the increasing of film thickness and diminishing of film transparencies.

  Abstract
  The pure and various metals (Ni and Ba) doped Cadmium Sulphide (CdS) nano particles were successfully synthesized by chemical co-precipitation method using analytical grade Cadmium Chloride and Sodium Sulphide chemicals. The prepared samples were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Optical absorption (UV- Vis) studies. The XRD results showed that the all prepared samples were polycrystalline with hexagonal structure. The peaks were identified and compared with JCPDS (File No. 89-2944) values. From the SEM studies, the particles agglomerations are decreased by the addition of metal dopants and the average grain size of the particles are found in the range 500 nm. The optical properties have been characterized. The obtained band gap values are 2.56 eV, 2.54 eV, 2.35 eV and 2.48 eV. The band gap is reduced and the crystallization is increased in the Ni and Ba doped CdS nano particles are more suitable for fabrications of Opto electronic studies.

  Abstract
  In the present work the growth of potassium dihydrogen phosphate crystal doped with nicotinic acid at various concentrations is reported. KDP is a well –known optical material having different applications in electro-optics and laser technology. Nicotinic acid doped KDP crystal is grown using slow solvent evaporation technique. The doping of nicotinic acid at various concentrations was successively achieved in KDP crystal and confirmed by Fourier transform infrared spectroscopy analysis. The modification of optical transmittance and other optical constants of KDP crystal due to the doping of nicotinic acid have been investigated by means of UV-visible spectral analysis. The dielectric behavior of the sample has been studied. The variation of the dielectric loss with frequency of the applied field is reported.
