A novel blue luminescent material Sr 6 Ca 4 (PO 4 ) 6 F 2 :Eu 2+
Source abstract
Abstract
Abstract For the first time, a series of novel blue light-emitting phosphors Sr6Ca4(PO4)6F2:Eu2+ were synthesized by a traditional solid-state reaction. The phosphors exhibited a broad and intense excitation band that could be pumped by near ultraviolet to exhibit a broad photoluminescence band ranging from 400 nm to 530 nm peaking at 452 nm. Quenching concentration was 0.05 mol. Furthermore, the mechanism of concentration quenching involving SCPF:Eu2+ was demonstrated to be a dipole–dipole interaction with critical distance of 27.95 A. Decay time curves were also measured to validate energy transfer, and quantum efficiency is investigated. The chromaticity diagram of Commission Internationale de l’Eclairage indicated that SCPF:Eu2+ may be used as a blue-emitting component for white light-emitting diode applications.
