In article number 1900412, Juan Du, Yuxin Leng, Miao Zhou, and co‐workers successfully fabricate single CsPbBr 3 /CdS core/shell structured quantum dots (QDs) by capping a CsPbBr 3 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 CsPbBr 3 /CdS QDs into microtubule resonators.
