## 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.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 1)

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

### Claim 4 (depends on 1)

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.

### Claim 5 (depends on 1)

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.

### Claim 6 (depends on 1)

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.

### Claim 7 (depends on 1)

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

### Claim 8 (depends on 1)

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

### Claim 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.

### Claim 10 (depends on 9)

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.

### Claim 11 (depends on 9)

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.

### Claim 12 (depends on 9)

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%.
