Abstract
Luminescence of CsPbX3-like quantum dots in CsX crystal host (X = Cl, Br) is reported. Single band spectrum is found for as grown or heavily annealed (T = 240 degrees C) CsX:Pb, while a family of emisssion band s is observed after annealing at temperatures below 210 degrees C. Ani sotropic growth of quantum dots in the early stage is proposed and pos itions of emission peaks are calculated for CsPbCl3 quantum dots using a simple model.
