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

“…This diffraction peak is due to the phase transformation and degradation of CsPbBr 3 into CsPb 2 Br 5 as a result of moisture incorporation into the crystal lattice. This is consistent with the reported instability of CsPbBr 3 in air and was previously observed in CsPb 2 Br 5 synthesized using different ratios of PbBr 2 and CsBr in water. , The PL spectrum taken after 2 weeks (see Figure b) shows a decreased intensity along with two emission peaks due to the mixture of CsPbBr 3 and CsPb 2 Br 5 . ,, After 8 weeks in air, the PL intensity further decreases and more peaks are observed. As expected, this result again demonstrates the instability of the bulk CsPbBr 3 under ambient conditions.…”

CsPbX3 nanocrystals embedded in hollow AlO(OH) nanosheet assemblies towards highly bright flexible multicolor emitting films

“…7 Many studies have focused on flexible films to obtain a diversity of luminescent material designs. [8][9][10][11] Due to their adjustable emitting range, high PL quantum yields (PLQYs), high color purity, and easy synthesis, all-inorganic perovskite NCs have aroused great interest. The perovskite NCs have become an outstanding candidate for light-emitting diodes (LEDs), photodetectors, solar cells, and lasers.…”

High piezoresponse in low-dimensional inorganic halide perovskite for mechanical energy harvesting
