Abstract

Abstract : In article number1900412, Juan Du, Yuxin Leng, Miao Zhou, and co‐workers successfully fabricate single CsPbBr3 /CdS core/shell structured quantum dots (QDs) by capping a CsPbBr3 QD core with a CdS shell. The core/shell QDs exhibit ultrahigh chemical stability and nonblinking photoluminescence. Furthermore, low threshold whispering‐gallery‐mode lasing with a high‐quality factor is achieved by incorporating CsPbBr3 /CdS QDs into microtubule resonators.
