Nonlinear medium glass used for semiconductor particle dispersed nonlinear optical glass and semiconductor particle dispersed nonlinear optical glass based thereon

摘要

The present invention relates to a medium glass used in a semiconductor microparticle dispersion type optical glass and a semiconductor microparticle dispersion type nonlinear optical glass based thereon. The composition of the medium glass used in the conventional semiconductor fine particle dispersion type optical glass and the semiconductor fine particle dispersion type nonlinear optical glass based thereon is excellent in the mechanical strength and light transmittance,₂-B₂O₃-Al₂O₃(Aluminoboro-silicate) glass having a basic component of K₂O-ZnO as a modifier. However,₂Aluminoborosilicate glass containing O-ZnO as a modifier has a disadvantage of high raw material cost, lack of technical know-how on the production method, high viscosity, and poor moility. Accordingly, the present invention relates to a glass bead glass having excellent light transmittance,₂O and CaO were added, and to improve the mechanical strength, Al₂O₃And to improve moility, GeO₂A composite metal oxide is compounded with a compound metal oxide, and the glass in which the semiconductor component is dissolved in a supersaturated state at room temperature is heat-treated under suitable conditions to precipitate semiconductor fine particles to produce nonlinear optical properties, transmittance, moility, durability and chemical resistance And a medium glass used for a semiconductor particle-dispersed nonlinear optical glass excellent in mass productivity can be produced. In addition, CuCl fine particle dispersion type nonlinear optical glass can be manufactured by using the developed medium glass.
