A method of making a material, the method comprising:
- melting a batch mixture comprising:
- 0<SiO2≤35 mol %;
- 30 mol %≤P2O5≤65 mol %, and
- 25 mol %≤CuO≤55 mol %;
- mixing the melt;
- cooling the mixture to form a glass, and
- annealing the glass without growing crystals in the glass such that the annealed glass is amorphous, single-phase.
