Paper Abstract

Photoluminescence and picosecond differential absorption spectra measurements of the CdSe quantum dots embedded in phosphate glass are reported. The dots are in the strong quantum confined regime (the mean particle radius, 2.9 nm). The photoluminescence spectra are observed to depend on excitation intensity: increasing of excitation leads to appearing of a new luminescence peak. The differential absorption spectra show bleaching accompanied by time- delayed induced absorption on the high energy side.
