Lead halide perovskites are intriguing semiconductors for lasers due to high quantum yield, tunable bandgaps and facile solution-process ability. However, limited by the weak optical confinement, continuous-wave (CW) pumped lasing, as one prerequisite for the electrically pumped lasing, is still cha...
