WebIn this work, the green emission of the CsPbBr 3 –Cs 4 PbBr 6 perovskite composites is studied using temperature dependent photoluminescence (PL). The PL spectra at different temperatures simultaneously contain two sub-peaks (520 nm and 550 nm), which are ascribed to the emissions of the band-edge and the defect trapped exciton of CsPbBr 3. WebIt is well known that surface passivation and modification are efficient approaches to improve the photoluminescence and stability of perovskites. Although CsPbBr3 nanocrystals (NCs) could be embedded into a Cs4PbBr6 matrix to enhance the photoluminescence property, the limited stability will hinder their ap Journal of Materials Chemistry C HOT Papers
