Stable continuous-wave lasing from discrete cesium lead bromide quantum dots embedded in a microcavity

{{output}}
All-inorganic cesium lead bromide (CsPbBr3) quantum dots (QDs) with high photoluminescence (PL) quantum efficiency have been reported as ideal gain materials for high-performance lasers. Nevertheless, isolated CsPbBr3 QDs have not achieved lasing emission (LE)... ...
