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%.
Claims21
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 at 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%.
1 more element
A method of forming a quantum dot-doped glass, the method comprising:
- modifying a borosilicate glass surface to create or modify pores within the glass without HF wherein the modified glass contains 0 to 0.1 wt % of F;
- treating the pores within the borosilicate glass with a solution comprising quantum dots to place the quantum dots into pores in the glass wherein the quantum dots within the glass have a photoluminescence quantum yield of ≥10%, and
- optionally sealing the quantum dots within the glass via one or more layers of optically transparent material to form the quantum dot-doped glass.
