THE Ghosh Research Group

The Ghosh Research Group at VIT-AP University, explores the intricate interactions between light and matter in advanced nanomaterials. The group’s research focuses on lead halide perovskites, semiconductor nanocrystals, and quantum dots, employing time-resolved spectroscopic techniques to investigate charge carrier behavior, electron-phonon interactions, and energy relaxation processes.

Integrating physical chemistry, nanoscience, and optoelectronics, the group aims to reveal how fundamental photophysical mechanisms determine the optical and electronic performance of emerging materials. Their work contributes to the development of efficient solar cells, light-emitting devices, and photonic technologies, advancing the understanding and application of modern functional materials.
