Abstract
The present disclosure relates to a quantum dot-doped glass and method of making the same. A quantum dot-doped glass includes glass that includes quantum dots in an internal structure of the glass. The quantum dots within the glass have a photoluminescence quantum yield of greater than or equal to 10%.

A quantum dot-doped glass comprising:
- glass comprising quantum dots in pores in the glass, wherein:
- (i) the glass comprises not greater than 0.1 wt % of F in a 100 nm deep layer adjacent to the external surface of the glass;
- and
- (ii) and the quantum dots situated within the glass have a photoluminescence quantum yield of ≥10%;
- and
- (iii) the quantum dots are 0.0001 wt % to 5 wt % of the quantum dot-doped glass, and wherein the quantum dots have a diameter of 1 nm to 50 nm.
