Enhancement of Photoluminescence Quantum Yield and Stability in CsPbBr(3) Perovskite Quantum Dots by Trivalent Doping

We determine the influence of substitutional defects on perovskite quantum dots through experimental and theoretical investigations. Substitutional defects were introduced by trivalent dopants (In, Sb, and Bi) in CsPbBr(3) by ligand-assisted reprecipitation. We show that the photoluminescence (PL) e...
