Paper Abstract

We have investigated the nonlinear absorption of CdSe-based nanoplatelets (NPLs) with different thicknesses of shell in the case of resonant one-photon stationary excitation of exciton transitions by nanosecond pulses of mode-locked Nd:YAP laser. Decrease in absorption at the wavelength of whether light hole – electron and heavy hole – electron exciton transitions was revealed. Induced changing of both absorption doublet components was attributed to phase space filling effect and exciton energy conversion mechanism.
