摘　　要：新型固态照明与显示技术具有亮度高、效率高、节能环保等显著优势,已成为室内外照明、汽车大灯、激光电视等高端照明和显示领域的主流技术。绿光发光材料作为荧光转换型照明与显示的核心材料,其性能直接决定器件的服役行为。然而,在高功率密度激光运转下,绿光发光材料的温度急剧升高,导致其量子效率下降、发光衰减,严重制约了固态照明与显示技术的应用。为此,不同物理形态的绿光发光材料应运而生。本文综述了激光显示用绿光发光材料的最新研究进展,系统地总结了粉末、陶瓷、微晶玻璃、薄膜等绿光发光材料在热稳定性、半高宽、色域、色度参数等性能特征的调控策略。讨论了绿光发光材料面临的发光效率和器件封装等挑战,并展望了照明与显示用绿光发光材料的研究进展。New solid-state lighting and display technologies have remarkble advantages of high brightness,high luminescence efficiency and environmentally friendly,which have become a technology with great application prospects for high-end lighting and display in the field of indoor and outdoor lighting,automotive headlights,laser TVs,etc.As the core material for fluorescent conversion lighting and display,the performance of green luminescent material undoubtedly determines the optical behavior of the device.However,under the operation of high-power density laser,the temperature of green luminescent material increases sharply,which leads to the decrease of quantum efficiency and luminescence attenuation,and seriously restricts the application of solid-state lighting and display technology.Therefore,different physical forms of green luminescent material came into being.In this paper,the latest research progress of green luminescent material for laser display is reviewed.The control strategies of the properties of green luminescent material,such as powder,ceramic,glass and film,in term of thermal stability,full width at half maximum(FWHM),color gamut and chromaticity parameters are summarized systematically.Finally,the challenges of green luminescent material such as luminescence efficiency and device packaging are discussed,and the research progress of green luminescent material for lighting and display is prospected.
