As a potential light material with applications in LED (LED) and radiation detection, low-dimensional halide perovskites (2D, 1D, and 0D) have emerged in recent years. There are a number of 0D metal halides with very high PLQEs (photoluminescence quantum efficiencies). Emission from lowdimensional metal halides is often quite diffuse. Depending on the substance, self-trapped excitons and defects may generate broadband radiation. A highly photoluminescent and stable inorganic CsCu2I3 perovskite single crystal (SC) was synthesized. The bulk of CsCu2I3 is made up of the Cu-I octahedron, which creates a 1D electronic structure by isolating electron states in two different orientations. Due to the structure, the recombination rate of exciton radiation is quite high. CsCu2I3 SCs, because of their unique electrical architecture, provide a substantial opportunity for energy reductions in this application.
