光致发光气凝胶研究进展

Photoluminescent aerogels，possessing the combined features of aerogels and luminescent materials，are a novel type of porous luminescent materials. Photoluminescent aerogels are characterized by unique properties，such as large specific surface area，high porosity，flexible structure，and controllable optical properties，and thus hold wide promise for diverse applications，particularly in sensing and optoelectronic devices. Focusing on photoluminescent aerogels，this review summarizes the preparation methods of aerogels，systematically introduces the aerogel according to the classification of luminescent centers，and discusses the application of the aerogel in the fields of sensing and optoelectronic devices. Finally，challenges and perspectives of photoluminescent aerogels are discussed.
