Colloidal CsPbX3 (X = Br, I, Cl) NCs: Morphology controlling, composition evolution, and photoluminescence shift

CsPbX3 (X = Cl, Br and I) and mixed CsPb(Cl/Br)3, CsPb(Br/I)3 with adjusting morphologies and phase composition, tunable photoluminescence wavelength, as well as high luminescent efficiency were synthesized through changing preparation parameters.229
