Abstract :
Absorption and emission patterns are mechanically drawn in order to understand the transitional movement of electron from one energy state to another involved in the mechanism of luminescence study. Both the lower state orbital kinetic energy of the electron as well as the kinetic energy gained by the same revolving electron due to the absorption of photonic energy are responsible during absorption transition for the jumping of electron from lower energy state to higher energy state. Thus, the electron is gained by an excess amount of kinetic energy for uplifting from lower level to upper level against the electrostatic pull. Similarly, both the upper state orbital kinetic energy of the electron and the electrostatic pull are responsible during emission transition for the putting of electron from higher energy state to lower energy state. On reaching at the depth of lower orbit, the electron is strictly prohibited to fall further accordingly. Therefore, at this moment as soon as the electron enters into it’s lower orbit, only the orbital component of kinetic energy required for the revolutionary motion remains with the electron. The rest part of the kinetic energy of the electron is transformed into the photonic emission of luminescence light.
