Paper Abstract

The authors report on optical investigation of CdSe-microcrystallites (MCs) embedded in glass and grown diffusion controlled to create MCs near the stage of nucleation having small radii (approximately equals 1.6 nm) and a symmetric size distribution. Room temperature measurements of (i) absorption bleaching and its kinetics at resonant MC-excitation using frequency doubled single ps-pulses from YAG-laser, and (ii) spectral hole burning at different delays in the ps-time scale, before and after a surface passivation of the samples by hydrogenation to remove MC- glass interface states responsible for the carrier transfer into the matrix, have been performed. After passivation, higher bleaching values, a slower recovery, and a blue shift of the DTS signal are obtained. A kinetic model including three levels and a fast carrier capture into the glass matrix is discussed to explain the observed nonlinear optical behavior.
