XI-YUE ZHANG, LE ZHANG, BING-HENG SUN, et al. Abnormal Thermal Quenching Effect of High Power Density Excited Fluorescent Materials. [J]. Chinese journal of luminescence, 2021, 42(10): 1458-1481. DOI: 10.37188/CJL.20210202.
荧光转换材料普遍存在的发光强度随温度升高而降低的热猝灭现象严重影响了器件的性能,限制了其在高功率发光二极管(LED)/激光二极管(LD)照明中的应用。然而,部分荧光材料却会出现随着温度升高发光强度增大的现象,即反常热猝灭效应。反常热猝灭作为提升发光材料及其器件应用性能的有效途径得到了广泛研究。本文总结了目前反常热猝灭效应在发光领域的研究现状及应用,阐述了发光反常热猝灭的机理,并对其未来发展趋势进行了展望,以期开发出具有更优反常热猝灭特性的新型发光材料,满足高效高功率LED/LD照明器件的应用需求。
Thermal quenching is a phenomenon that the luminescence intensity of fluorescent conversion materials decreases with the increase of temperature
and it seriously affects the performance of the devices and limits the applications in high power LED/LD lighting. However
the luminescence intensity of some fluorescent materials often increases with the rise of temperature
which is named as the abnormal thermal quenching effect. As an effective way to improve the performance of luminescent materials and devices
the abnormal thermal quenching effect has been widely studied. In this paper
the research status and application of fluorescent materials with abnormal thermal quenching effect was reviewed
the mechanism of abnormal thermal quenching effect was illustrated
and its future development trend was prospected. This review will help to develop new luminescent materials with better abnormal thermal quenching characteristics to meet the application requirements of high efficiency and high power LED/LD lighting devices.
