Photoluminescence signature in Eu3+ ion doped NaCdPO4 phosphors for white LEDs application

Abstract

The Eu3+ doped phosphate based phosphors NaCdPO4 hosts were prepared by solid-state reaction. The effects of the crystalline host and the incorporation of a sensitizer Eu3+ on the luminescence characteristics of the specimen phosphors were studied. NaCdPO4 was investigated for its structural and luminescence properties, as a possible host material for efficient phosphors. Prepared phosphors were characterized by photoluminescence technique possesses a 320 nm excitation maxima and emission broad peak appears at 637 nm indicating a possible red phosphor for UV excitation operated white LED application.
