Paper Abstract

Photoluminescence (PL) features and nonlinear transmission of Cu-doped CdSe colloidal quantum dots (QDs) under nanosecond laser pulses excitation were investigated. Strong difference of the pump intensity dependent behavior of basic exciton transition and Cu dopants associated PL was revealed. The presence of exciton-phonon interaction and its strong influence on the PL and nonlinear properties of Cu-doped colloidal CdSe QDs are proved by the simultaneous linear growth of basic excitons PL, the growth of the Stokes shift and significant decrease of absorption at the basic exciton transition wavelength with the increase of pump intensity [1].
