WebMay 15, 2024 · The slow decay originates from band-to-band transition of QDs intrinsic energy band while the faster decay originates from the transition of exciton energy band to value band [ 12 ]. The schematic diagram of energy level of the blue-green bimodal luminescence is depicted in Fig. 2 (f). WebJan 6, 2024 · CsPb 2 X 5 is characterized by its possession of a wide band gap in the deep ultraviolet region due to limited conjugation within the two-dimensional layer crystal lattice. In Cs 4 PbBr 6 , the PbX 6 4– octahedral unit is completely detached from the conjugation of the band structures, making the perovskite less susceptible to the external ...
