WebSep 9, 2024 · Optical and structural characterizations of CCAC microcrystals (MCs) and nanocrystals (NCs) confirm the growth, the existence of direct bandgap, and <111> oriented monoclinic crystal phase of space group C2/m. Interestingly, both the MCs and NCs display an almost equal bandgap of 1.1 eV in thin film even though they have higher … WebDouble perovskites (DPs) with a generic formula A 2 M′(I)M III X 6 (A and M are metal ions, and X=Cl, Br, I) are now being explored as potential alternatives to Pb-halide perovskites for solar cells and other optoelectronic applications. However, these DPs typically suffer from wide (≈3 eV) and/or indirect band gaps. In 2024, a new structural variety, namely layered … photo editing with slimming effect
