For the first time, we have synthesized APbBr3 (A = Cs+/MA+/FA+, where MA+ = CH3NH3+ and FA+ = CH(NH2)2+) bulk as well as nanoparticles (NPs) by solid-state reactions at room temperature. This facile strategy yields different shape structures e.g. square and rectangular (CsPbBr3), spherical (MAPbBr3) and parallelogram (FAPbBr3) NPs.
