Abstract:

The luminescence properties of Sr2GdTaO6 have been studied by keeping Eu(3+) as constant concentration and varying Er(3+) concentration. Sr2GdTaO6 phosphor doped with rare earth ions of Eu and Er having monoclinic phase of space group P21/n was synthesized, and their photoluminescence properties have been examined under UV excitation of wavelength 265 nm and 275 nm. PL emission exhibited around 468, 475, 580, 596, and 610 nm wavelength subsequently for various concentrations of Er(3+) for two different excitation wavelengths. By using xenon lamp as source and corresponding wavelength having excitation wavelength 265 and 275 nm, it is observed that the maximum light emission yield in region presenting a color-correlated temperature in the range of 1500-1900 K and 3000-6000 K.
