摘　　要：激光照明用荧光材料已成为固态照明领域的研究热点。随着相关研究的不断深入和细化,科研人员对于荧光材料的认知也在不断提升。然而,现有激光照明用荧光材料的设计和研究思路在很大程度上仍受到wLED产业的影响,在材料器件化的过程中会存在种种问题。本文旨在从工程应用角度出发,探讨激光照明用荧光材料应具备的核心特性。首先简述荧光材料应用于激光照明和大功率wLED场景下的区别;其次指出一些现有荧光材料设计和表征中存在的误区;再次归纳荧光材料在面向激光照明应用时的设计规则及其机理;然后,介绍一些商用荧光材料的设计和封装方案,并探讨几种潜力较好的材料设计和制备方案;最后,展望相关研究的发展趋势。In the field of solid-state lighting,phosphors for laser lighting have been becoming a hotspot of the cur-rent research.With extensive research and fruitful results appeared,researchers have improved a deeper understand-ing of phosphors for laser lighting.However,current design and investigation of phosphors for laser lighting are still highly influenced by wLED industry,resulting in that plenty of theoretically“good”phosphors are actually not suit-able for laser lighting applications.The aim of the present study is to clarify the key properties of phosphors for laser lighting from an application perspective.Firstly,the difference between the phosphors for laser lighting and for high-power wLED is discussed.Secondly,the misunderstandings in the design and characterization of current phosphors are pointed out.Thirdly,the novel design principle and the related mechanisms are summarized.Lastly,the design and packaging schemes of some commercial phosphors are introduced,several promising material design schemes are presented,and the development trend of related research is prospected.
