Abstract

This paper investigates the manipulation of excitons in lead halide perovskite nanocrystals (CsPbBr3 NCs) via coherent light-matter interaction. The researchers observe an anomalous enhancement of the exciton energy shift at room temperature with increasing control-light wavelength, attributed to large dipole moments in interconduction band transitions between spin-orbit split states. This leads to a crossover from the two-level optical Stark effect to the three-level Autler-Townes effect, enabling efficient coherent optical manipulation of excitons at room temperature and extended control-light wavelengths.
