Chalcogenide glass-ceramic having, for example, the following composition GeSe&#x2014;SbSe&#x2014;CuI, this glass-ceramic comprising at least one crystalline phase, characterised in that the crystallisation rate and the dimensions of the crystals in the crystalline phase are such that the crystals are substantially in contact with each other in such a way that this crystalline phase has an electrical conductivity greater than or equal to 10s&#xb7;cmwhich increases under lighting due to the creation of charge carriers within the crystalline phase.

Chalcogenide glass-ceramics with photoelectric properties and method for the manufacture thereof

The invention relates to vitreous compositions, in particular of the vitroceramic type, transparent to infrared, production and uses thereof. Said compositions comprise in mol. %: Ge 5-40, Ga&#x3c;1, S+Se 40-85, Sb+As 4-40, MX 2-25, Ln 0-6, adjuncts 0-30, where M=at least one alkaline metal, selected from Rb, Cs, Na, K and Zn, X=at least one atom of chlorine, bromine or iodine, Ln=at least one rare earth and adjunct=at least one additive comprising at least one metal and/or at least one metal salt with the sum of all molar percentages of the components present in said composition being 100.
