## Abstract

An article that can include a glass including SiO2 from 25 mol % to 99 mol %, Al2O3 from 0 mol % to 50 mol %, WO3 plus MoO3 from 0.35 mol % to 30 mol %, and R2O from 0.1 mol % to 50 mol %. R2O is one or more of Li2O, Na2O, K2O, Rb2O and Cs2O. R2O minus Al2O3 is from −35 mol % to 7 mol %. The glass includes at least one of: (i) RO from 0.02 mol % to 50 mol % and (ii) SnO2 is from 0.01 mol % to 5 mol %. RO is one or more of MgO, CaO, SrO, BaO and ZnO. The article can also include a glass-ceramic with at least one and one crystalline phase comprising an oxide, from 0.1 mol % to 100 mol % of the crystalline phase, of at least one of: (i) W, (ii) Mo, (iii) V and an alkali metal cation, and (iv) Ti and an alkali metal cation.
