A method for incorporating quantized particles of colloidal semiconductors in transparent silicate glasses has been developed. The absorption spectra of the particles in the glasses are identical to those of the starting colloidal aqueous solutions. The luminescence intensity of colloidal semiconductors in silicate glasses is much higher than that for colloids in liquid solutions. This is attributed to passivation of surface recombination sites by the silicate polymer.
