ABSTRACT:
The semiconductor-containing glass disclosed herein is a semiconductor-containing glass which is produced by a sol-gel technique and which includes a semiconductor-containing glass characterized in the composition of a glass matrix and a semiconductor-containing glass characterized in the composition of a semiconductor. Either a semiconductor-containing glass has useful properties as a non-linear optical material.
The method of producing semiconductor-containing glass disclosed herein is a method in which oxidization, volatilization or decomposition of a compound semiconductor or volatilization of a constituent element of the compound semiconductor by heat treatment for forming glass from a gel solid can be suppressed when a semiconductor-containing glass in which the compound semiconductor is dispersively precipitated is produced by a sol-gel technique. That is, the method disclosed herein is a method in which a semiconductor-containing glass containing a compound semiconductor dispersively precipitated therein at a high concentration can be produced. The method is characterized in the technique of dispersively precipitating a compound semiconductor.
