摘要：
A novel method to prepare orthophosphate LiSrPO4: Lu2+ phosphor for white light-emitting diodes (w-LEDs) is given in this paper. Phosphor was successfully synthesized by Pechini (citrate gel) method which is efficient than conventional high temperature solid state reaction. X-ray powder diffraction (XRD) analysis confirmed the single phase formation of LiSrPO4:Eu2+ with monoclinic crystal structure. Luminescence results showed that the phosphor could be efficiently excited by near UV and exhibited bright blue emission at lambda(em) = 420 tun corresponding to 5d- 4f transition of Eu2+. The phosphor exhibits blue emission bands under 350 rim excitation. This mercury-free excitation is useful for solid state lighting and light-emitting diode (LED). Hence it could be useful for solid state lighting and light-emitting diode (LED) application.
