1. A device comprising:
a substrate comprising a glass or glass-ceramic material comprising about 0.1% to about 50% by weight crystalline phase;
the substrate comprising an unbleached region and a bleached discrete region comprising at least partially dissolved or altered crystalline phase wherein an average ratio of absorbance in the unbleached/bleached regions over the near infra-red (NIR) wavelength range of 700-2000 nm is equal to or greater than 7.5;
wherein the substrate is substantially opaque in the visible wavelength range of 400 nm to 700 nm and the unbleached region exhibits an average absorbance of 1.0 OD/mm or greater in the visible wavelength range of 400 nm to 700 nm; and
wherein the substrate includes a modifiable crystalline phase consisting of an oxide or sub-oxide comprising tungsten and/or molybdenum that may be doped with any combination of: Li, Na, K, Rb, Cs, Be, Mg, Ca, Sr, Ba, Ra, Ti, Zn, Se, Nb, Ru, Rh, In, Sn, Pb, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu, wherein this modifiable component amount is about 0.35 mol % to about 30 mol %.
