Preparation and luminescence of new Nd3+ doped chloro-sulphide glass–ceramics

Chalcogenide glass–ceramics containing rare earth have been studied. A reproducible process has been established for making transparent glass–ceramics. The presence of micro-crystals inside the chalco-halide glass–ceramics induces scattering at the short wavelengths. Photoluminescence of rare earth has been greatly increased in glass–ceramics. To our best knowledge, this is the first paper on rare-earth-doped glass–ceramics based on chalcogenide.
