Abstract

A novel blue phosphor based on phosphate host matrix, KSrPO₂ doped with Eu²⁺, was prepared by solid state reaction. The phosphor invariably emits blue luminescence with a peak wavelength at 424 nm under ultraviolet excitation at 360 nm. Eu²⁺-doped KSrPO₄ phosphors show higher thermally stable luminescence which was found to be better than commercially available Y₃Al₅O₁₂:Ce ^3- phosphor at temperature higher than 225°C.
