Exploring Morphology-Driven Optoelectronic Properties of CsPbCl3 Perovskite Nanoplatelets, Nanorods, and Quantum Dots
摘要
The exceptional optical and electronic properties of perovskites have made them highly promising for advanced optoelectronic applications. This study investigates the role of morphological variations and charge transfer properties of CsPbCl3 perovskite nanostructures, including, nanoplatelets, nanorods and quantum dots synthesized via ligand-assisted precipitation methods. Structural characterization using XRD and TEM reveals distinct morphologies and phase behaviours, optical analysis highlighting the bandgap modulation, photoluminescence, and defects. Charge transfer studies, conducted with redox-active Anthraquinone, demonstrate significant morphology-dependent differences in surface interaction and charge separation dynamics. Quantum dots exhibit superior optical performance and low defects, making them ideal for precise optoelectronic applications. The nanorods with structural anisotropy, demonstrate improved charge transfer, while nanoplatelets, demonstrated a broad optical absorption and highest charge transfer efficiency. These findings deepen the understanding of structure-property relationships in CsPbCl3, providing insights for tailoring materials for next-generation energy and photonic technologies.
