Advances in Luminescence Thermal Enhancement of Rare Earth Activated Phosphors
Since the size-dependent up-conversion fluorescence thermal enhancement phenomenon was found in rare earth-activated nano-fluorescent materials,the development of materials with noteworthy fluorescence thermal enhancement effect has become a research hotspot.Recent explorations have found that the fluorescence thermal en-hancement effect can be achieved in non-nanoscale fluorescent material systems and non-up-conversion luminescence processes,which will further expand the application scenarios of this interesting optical phenomenon.In this review,the latest research progress of rare earth-activated fluorescent thermal enhancement materials is summarized.The proposed mechanisms and potential applications of rare earth-activated fluorescent thermal enhancement materials are overviewed,and the research directions are outlooked.
