Synthesis and Spectral Properties of La4-x(P2O5)3:Eux
Abstract:
La4-x(P2O5)3:Eux were synthesized from a mixed solution of La(NO3)3 and Eu(NO3)3 in nitric acid solution(pH=4.5) followed by precipitation on addition of Na4P2O7 solution and calcination at 900℃. The products showed a highest excitation peak at 349 nm and highest emission peak at 596 nm.
