Study of Photoluminescence of ZnO: Li Phosphor

Y. D. Tembhurkar [18]


Abstract: Luminescence is process by which under the influence of an exciting agent, matter generates non-thermal radiation, characteristic of a particular luminescence material. Study reveals that particle size of the phosphors increases with firing temperature and reaches an average of about 30-40 m. Therefore three excitation peak observed at the wavelength 261.2 nm (4.752 eV), 273.2 nm (4.543 eV) and 284.8 nm (4.370 eV). The peak at 261.2 nm was maximum intensity it is used for study emission spectra. Similarly five emission peaks observed namely 407.68 nm (3.044 eV), 423 nm (2.934 eV), 446 nm (2.78 eV), 468 nm (2.652 eV) and 492 nm (2.62 eV). Maximum intense peak detected at wavelength 468 nm (2.62 eV). The photoluminescence in ZnO doped Li shows donor impurity introduces some defects in the pure crystal structure.
