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%.
Claims15
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 in a 100 nm deep layer adjacent to the glass surface;
- 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,
- wherein 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.
