红色荧光粉Mg2TiO4∶Mn4+的制备及发光性能
Preparation of red phosphor Mg2TiO4∶Mn4+ and its luminescent properties
摘要
Abstract
Mn4+-activated Mg2TiO4∶ Mn4+ red phosphor was prepared by the solid-state reaction,and its structure and luminescent properties were investigated in detail.This phosphor with a broad excitation band in UV and blue light regions shares an intense red emission at 660 nm,which is due to the 2E2→ 4A2 transitions of Mn4+.The optimized sample was obtained by adjusting the concentration of Mn4+.Finally,the warm light-emitting diode was obtained by coating optimized Mg2TiO4∶0.002 5 Mn4+ with YAG on GaN chip,which exhibited an intense warm white light.关键词
