Confined acoustic phonons in CsPbI3 nanocrystals explored by resonant Raman scattering on excitons

Carolin Harkort, Ina V. Kalitukha, Nataliia E. Kopteva +8

Optical properties of the lead halide perovskites nanocrystals are controlled by confined excitons and rich spectrum of confined acoustic and optical phonons. We study experimental…
