Synthesis and photoluminescence properties of MZr2(PO4)3:Eu3+; Bi3+ (M=Na; K) phosphors

Abstract

Abstract:A series of new red phosphors, MZr 2 (PO 4 ) 3 :Eu 3+ ; Bi 3+ (M=Na; K), were synthesized using the solidstate reaction method, and their photoluminescence spectra were measured. The MZr 2 (PO 4 ) 3 :Eu 3+ ; Bi 3+ (M=Na; K) phosphors were efficiently excited by an ultraviolet (UV; 395 nm) source, and showed intense orange-red emission at 595 nm. Further investigation of the concentration-dependent emission spectra indicated that the MZr 2 (PO 4 ) 3 :Eu 3+ ; Bi 3+ (M=Na; K) phosphors exhibit the strongest luminescence intensity when y = 0.01 in NaZr 2(0 95− ) (PO 4 ) 3 :Eu
