Method for manufacturing semiconductor particle-dispersed nonlinear optical glass

摘要

The present invention relates to a method for producing a semiconductor particle-dispersed nonlinear optical glass which is excellent in nonlinear optical characteristics and can be used as a core material for manufacturing a full-wave element. In the conventional method for producing a semiconductor particle-dispersed nonlinear optical glass, in the case of the melting and re-precipitation method, evaporation of a semiconductor component due to high-temperature melting and oxidation of Cu ions during melting of the semiconductor component CuC1 are performed, And the nucleation and nucleation of the semiconductor particles occur at the same time during the melting process. Therefore, there is a problem that the particle size distribution of the precipitated semiconductor particles is not uniform and wide. In order to solve this problem, the present invention provides a method of manufacturing a glass substrate, A primary melting step of sufficiently melting the medium glass at a high temperature for a long time; Cooling the melted medium glass; Pulverizing the cooled medium glass; Adding and mixing CuCl powder and a reducing agent powder to the milled glass medium; A secondary melting step of melting the mixture at a low temperature for a short time; Cooling and molding the glass melter containing CuCl; And heat treating the glass melter to deposit CuC1. The present invention also provides a method for producing a semiconductor particle-dispersed nonlinear optical glass.
