Study of Inorganic Halide (Cs2CuCl4) Perovskite Quantum dots for Energy Harvesting Devices

Abstract:

In recent days, there has been growing interest in metal halide inorganic perovskite quantum dots due to their promising diverse applications in the field of energy harvesting devices. Here, inorganic Cs₂CuCl₄ perovskite quantum dots were prepared by facile re-precipitation technique at room temperature. Inorganic Cs₂CuCl₄ QDs exhibited a quasi-spherical structure with a size of 5nm.  As synthesized quantum dots indicate bright and broad bluish-green emission when the sample is excited below 300nm, inorganic perovskite QDs possess novel morphology and high quantum yield. These Inorganic perovskites provide a magnificent quantum yield (90%) more extensive than any other Quantum dots. The most crucial intent of this work is to investigate a novel material for various research applications and motivate the researchers to explore the potential of the material. These QDs make use of light-emitting diodes, photodetectors, and Solar cells are also highly motivated.
