A study on the luminescent properties of new green-emitting SrIn_2O_4:xTb phosphor

摘要

The new green-emitting phosphors SrIn_2O_4:xTb (x = 0.125, 0.5 and 2%) have been prepared by solid state reaction at 1200℃. With different levels of Tb~(3+) doping, the X-ray diffraction, photoluminescent properties, integrated fluorescence intensity, fluorescence decay lifetime and chromatic characteristics of the phosphors have been systematically investigated.
