Emission wavelength control of CsPb(Br 1−x Cl x ) 3 nanocrystals for blue light-emitting diode applications

A facile synthetic method of CsPb(Br 1−x Cl x ) 3 halide perovskite nanocrystals, which emit light with the wavelengths ranging from green to blue based on an anion exchanging reaction using a halide exchange additive was reported.
