In recent years, the development of perovskite quantum dots (PQD) has played a significant role in all-inorganic cesium lead halide. CsPbX_3 (X= Cl, Br, I) perovskite quantum dots (PQD) have been discovered to be potential luminescent candidates for optoelectronics and future energy applications due to their optoelectronics characteristic. Perovskite has many advantages, including high performance and low cost leading to a great development opportunity, with a promising future in the engineering industry in relation to LED development. Perovskite nanocrystals are potential emitting materials for illumination and display applications, making them a viable option for various optoelectronic devices. Perovskite quantum dots (PQD) experience a significant limitation in their growth. In this project, we aim to improve the quality and efficiency of Perovskite quantum dots (PQD), with experiments on enhancing its stability using synthesis methods. This experiment will focus mainly on the microwave-assisted synthesis method and its development towards a more stabilized perovskite quantum dots (PQD), thus improving its stability which is the primary focus of this project.
