Problems solved by technology

However, currently In 2 S 3 There are few studies on the preparation of quantum dots introduced into solid materials, and there is no research on In 2 S 3 Related reports on the research of quantum dot glass in the field of nonlinear optics
[0004] At present, the preparation of glass mainly uses high-temperature melting method, but this method needs to be carried out at high temperature, which does not meet the requirements of energy saving and environmental protection, and agglomeration phenomenon is prone to occur at high temperature, which makes the uniformity of the prepared glass poor.

Abstract

The invention discloses sodium borosilicate glass doped with In2S3 quantum dots and a preparation method thereof. According to the sodium borosilicate glass doped with the In2S3 quantum dots, the In2S3 quantum dots are uniformly doped into sodium-borosilicate-based glass, and the sodium-borosilicate-based glass contains the following ingredients in percentage by mass: 5-15% of Na2O, 15-30% of B2O3 and 55-80% of SiO2; and the doped amount of the In2S3 quantum dots is 0.1-5.0% of the mass of the sodium-borosilicate-based glass. The sodium borosilicate glass doped with the In2S3 quantum dots is prepared in a manner that a sol-gel method is combined with atmosphere control, has excellent third-order nonlinear optical performance and heat stability, and has high light transmittance in visible-infrared regions, thereby being an important candidate material which is expected to produce high-speed full-light logic devices.
