Claim Text:
1. A chalcogenide glass-ceramic, comprising: at least one crystalline phase; and a composition comprising, as a molar %, where M is Cu, X is a halogen, and a sum of all the molar percentages of the composition is equal to 100, wherein a crystallisation rate in the crystalline phase and dimensions of crystals in the crystalline phase are such that the crystals are substantially in contact with each other, wherein the crystallisation rate in the crystalline phase and the dimensions of the crystals in the crystalline phase are such that the crystalline phase has an electrical conductivity greater than or equal to 10 wherein the electrical conductivity increases under lighting due to a creation of charge carriers within the crystalline phase.
