摘　　要：上转换光致发光属于反斯托克斯发光过程,可以将低能量(低频率、长波长)的激发光转变成高能量(高频率、短波长)的发射光,实现频率或能量的“上转换”光致发光。文章介绍了上转换光致发光的基本原理,并概述了上转换发光在不同领域中的应用研究进展,包括生物医学、太阳能电池、光学超分辨成像、传感与检测、指纹提取、防伪印刷、作物种植等。随着科学技术的发展和相关研究工作的深入,上转换发光有望扩展到更宽广的应用领域中去。The upconversion photoluminescence belongs to anti-Stokes luminescence process that converts low-energy(low-frequency,long-wavelength)excitation light into high-energy(high-frequency,short-wavelength)emissions,to achieve"upconversion"photoluminescence of frequency or energy.The basic principle of upconversion photoluminescence is introduced,and the application research progress of upconversion photoluminescence in different fields is summarized,including biomedicine,solar cells,optical super-resolution imaging,sensing and detection,fingerprint extraction,anti-counterfeiting printing,crop planting and so on.With the development of science and technology and the deepening of related research work,upconversion luminescence is expected to expand to a wider range of application.
