Abstract

A glass-ceramic includes a silicate-containing glass and crystals within the silicate-containing glass. The crystals include non-stoichiometric tungsten and/or molybdenum sub-oxides, and the crystals are intercalated with dopant cations.

First claim

What is claimed is:

1. A glass-ceramic, comprising:
silicate-containing glass; and
crystals within the silicate-containing glass, wherein the crystals comprise non-stoichiometric tungsten and/or molybdenum sub-oxides and the crystals are intercalated with dopant cations.

2. The glass-ceramic of claim 1 , wherein the crystals have a length of from about 1 nm to about 200 nm as measured by Electron Microscopy.

3. The glass-ceramic of claim 1 , wherein the crystals are homogenously distributed within the glass-ceramic.

4. The glass-ceramic of claim 1 , wherein the glass-ceramic has transmittance of about 5%/mm or greater over at least one 50 nm-wide wavelength band of light in a range from about 400 nm to about 700 nm.

5. The glass-ceramic of claim 1 , wherein the dopant cations are of H, Li, Na, K, Rb, Cs, Ca, Sr, Ba, Zn, Ag, Au, Cu, Sn, Cd, In, Tl, Pb, Bi, Th, La, Pr, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb, Lu, U, Ti, V, Cr, Mn, Fe, Ni, Cu, Pd, Se, Ta, Bi, and/or Ce.

6. The glass-ceramic of claim 1 , wherein at least some of the crystals are at a depth of greater than about 10 μm from a surface of the glass-ceramic.

7. The glass-ceramic of claim 1 , wherein the crystals have rod-like morphology.

8. The glass-ceramic of claim 1 , wherein volume fraction of the crystals in the glass-ceramic is from about 0.001% to about 20%.

9. A glass-ceramic, comprising:
a silicate-containing glass phase, and
a crystalline phase comprising sub-oxides of tungsten and/or molybdenum forming solid state defect structures in which holes are occupied with dopant cations.

10. The glass-ceramic of claim 9 , wherein the glass-ceramic has transmittance of about 5%/mm or greater over at least one 50 nm-wide wavelength band of light in a range from about 400 nm to about 700 nm.

11. The glass-ceramic of claim 9 , wherein the dopant cations are of H, Li, Na, K, Rb, Cs, Ca, Sr, Ba, Zn, Ag, Au, Cu, Sn, Cd, In, Tl, Pb, Bi, Th, La, Pr, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb, Lu, U, Ti, V, Cr, Mn, Fe, Ni, Cu, Pd, Se, Ta, Bi, and/or Ce.

12. The glass-ceramic of claim 9 , wherein volume fraction of the crystalline phase in the glass-ceramic is from about 0.001% to about 20%.
