Two-Dimensional Quantum-Confined CsPbBr3 in Silicene for LED Applications

Abstract: Perovskites with reduced dimensions are very attractive for LED applications due to their improved stability and efficient energy transfer. This is exemplified by 2D perovskites reported in the literature, predominantly either Dion-Jacobson or Ruddlesden–Popper systems, which typically use long chain alkyl moieties as spacers in order to form 2D layers. Here, we report an approach which uses an inorganic 2D materialsiliceneas a template to form two-dimensional quantum-confined CsPbBr3 (qc-CsPbBr3) layers of … Show more

“…As a rising star among semiconductor nanomaterials, CsPbBr 3 NSs have garnered global research interest due to their high photoluminescence quantum yield (PLQY), efficient photo-induced charge transfer, tunable spectral continuity, high color purity, and straightforward synthesis methods [ 1 , 2 , 3 , 4 ]. CsPbBr 3 has made significant scientific progress in the fields of solar cells [ 5 , 6 , 7 ], light-emitting diodes [ 8 , 9 ], display technologies [ 10 , 11 ], and lasers [ 4 , 12 , 13 ]. These achievements have not only driven the rapid development of related optoelectronic performance and materials research but, compared to other common materials used for catalysis ( Table 1 lists the advantages and disadvantages of common electrocatalytic/photocatalytic materials), perovskite structures also exhibit a higher tolerance for defects.…”
