Abstract :
The properties of MgS thin film crystals doped with locally grounded black velvet tamarind (VT) shell and deposited using a sol-gel method were investigated in the work to determine their suitable area applications. Freshly prepared solutions of sodium silicate, tartaric acid, magnesium nitrate and thiourea were the precursors used, while solution drops of the locally prepared grounded black velvet tamarind shells served as dopant. The grown crystals were subjected to thermal annealing at temperature of 104 OC and subsequently characterized to investigate their structural, optical and compositional properties for device applications. The results of our characterizations showed that the grown films have crystalline structures and the crystallite sizes are in the range of 19.406-29.243 nm while the micro-strain is in the range 4.92x10-3-7.531x10-3 and are influence by doping with VT. The EDS analysis showed that Mg, S as well as O were detected in the films and the atomic % of Mg has maximum value of 73.60 % for 1 drop VT/MgS, while the atomic % of sulphur in the samples increased from 4.20 % to 13.0 % as the number of drops of VT increased to 3 drops. FT-IR analysis showed that the films composed of =C-H stretch and C=C aromatic compounds but the presence of O-H as the number of VT drops increased to 3 drops. The films have low absorbance value but the film grown with 1 drop of VT doping has high value in the range of 0.5 – 1.1 in the near VIS (350 – 400 nm) region. The direct bandgap energy of the films was found to decreased from 3.42 eV to 3.20 eV as a results of doping MgS with VT drops. These properties exhibited by the grown thin films of un-doped MgS and VT/MgS make them suitable for many optoelectronics applications.
