共掺Tm3＋离子对CaAlSiN3∶Eu2＋红色荧光粉发光性能的影响
Influence of Tm3+ Codopant on Luminescence Properties of CaAlSiN3∶Eu2+ Phosphor
摘要
Abstract
A series of Eu2+single doped and Tm3+co-doped CaAlSiN3 phosphors were synthesized by high temperature solid-reaction method .Photoluminescence , afterglow emission and thermoluminescence glow curve investigations indicate that CaAlSiN3∶0.1%Eu2+sample possesses excellent photoluminescence properties with broad emission band located at about 630 nm.The introduction of Tm 3+codopant creates new emission bands located 654 nm and 800 nm, respectively, which are originated from Tm3+in CaAlSiN3 matrix.However, the Tm3+codopant causes the disappearance of 89.0 ℃ thermoluminescence glow peak , which indicates that the introduction of Tm 3+has changed the defect distribution and their concentrations , thus deceasing the visible 630 nm red light afterglow of CaAlSiN 3∶Eu2+.关键词
