摘要

激光照明是下一代大功率固体照明重要的发展方向之一。目前，主流白光激光器件所采用的黄光/绿光陶瓷或晶体的发射光谱中红光组分不足，使得采用这类单一材料的激光照明器件色温偏高、显色指数较低。本文报道了液相法制备的高效率高稳定的Rb,2,SiF,6,∶Mn,4+, (RSFM)红光单晶，该材料具有宽带蓝光吸收(~450 nm)和窄带红光发射(~630 nm)特征，外量子效率达55.8%。利用该材料组装的暖白光激光照明器件在7 W/mm,2,功率密度激发下，光效达104.3 lm/W、色温为2 633 K、显色指数为78.3。研究表明，高性能Mn,4+,激活氟化物红光单晶有望促进暖白光激光照明应用。

Abstract

Laser lighting is one of the important developing directions in solid-state lighting in the future. At present, the main stream laser lighting devices are fabricated by yellow/green ceramics or crystals, which show high color temperature and low color rendering index due to the insufficient red-light component of a single material. Herein, Rb,2,SiF,6,∶Mn,4+,(RSFM) red-emitting single crystal with high efficiency and high stability was prepared by a simple solution growth method. The RSFM single crystal shows broadband blue light absorption(~450 nm) and narrowband red emission(~630 nm). The external quantum efficiency(EQE) of RSFM crystal is up to 55.8%, showing great potential in laser lighting to improve the color quality. Under the excitation of 7 W/mm,2, a warm white laser diode device with high luminous efficiency of 104.3 lm/W, correlated color temperature of 2 633 K and a color rendering index of 78.3 is presented. The development of high-performance Mn,4+,-activated fluoride single crystals is expected to provide new insights into the development of highly efficient and stable materials for advanced lighting applications.
