全无机胶体铯铅卤化物钙钛矿量子点（CsPbX_3，X = Cl，Br，I）是一类新型的光增益材料，兼有胶体量子点和卤化物钙钛矿的优点。低阈值和超稳定的受激发射在大气条件下，通过尺寸或成分控制在整个可见光谱的波长可调谐性。
All-inorganic colloidal cesium lead halide perovskite quantum dots (CsPbX3, X = Cl, Br, I) are revealed to be a new class of favorable optical-gain materials, which show combined merits of both colloidal quantum dots and halide perovskites. Low-threshold and ultrastable stimulated emission is demonstrated under atmospheric conditions with wavelength tunability across the whole visible spectrum via either size or composition control.
