| Summary: | All-inorganic perovskite semiconductor nanocrystals exhibit high photoluminescence efficiency and hold significant potential for applications in visible light optical communication. In this study, a room-temperature resting method was developed to synthesize CsPbI3 nanocrystals, eliminating the need for heating, stirring, or ultrasound. This approach offers a straightforward, energy-efficient preparation process. By precisely controlling the micro-solubility of Cs2CO3 and PbI2 in the reaction solution, we facilitated the nucleation and growth of CsPbI3 nanocrystals at room temperature. The synthesized nanocrystals exhibit both linear and block-like morphologies with excellent optical properties. Moreover, slight increases in reaction temperature enable effective control over size distribution and luminescence characteristics. Experimental results demonstrate the potential application of CsPbI3-based liquid luminescent antennas in visible light communication, with signal stability and bit error rate measurements indicating promising commercial prospects for low-cost optical devices. |
