All-Inorganic Colloidal Perovskite Quantum Dots: A New Class of Lasing Materials with Favorable Characteristics

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 ­dem...

Description
Summary: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.
