UV irradiation may significantly alter the fluorescent surface groups of semiconductor quantum dots. The fluorescent carboxylic acid group‐related surface defects of the colloidal cubic silicon carbide quantum dots show reversible photobleaching upon exposure to UV light, and this phenomenon can be utilized to sense the solar UV irradiation with high accuracy. More details can be found in article number 1900272 by Dejian Dai, Chengyu Zhang, Wei Lu, Jiyang Fan, and co‐workers.
