Optical Properties Of CdSSe Microcrystallites In Glasses

We investigate the linear and nonlinear optical properties of semiconductor doped glasses. In thin samples we observed quantizied electron levels in absorption measurements. In the luminescence spectra we see a blue shift of the high energy side with increasing excitation. For nonlinear optical investigations we used spectroscopy with laser-induced gratings. We have seen optical bistability due to bleaching of the electronic transitions and due to photothermally induced absorption.
