    摘要: The invention is directed to chalcogenide glasses suitable for use in plastics forming processes. The glasses have the general formula YZ, where Y is Ge, As, Sb or a mixture of two or more of the same; Z is S, Se, Te, or a mixture of two or more of the same; and Y and Z are present in amounts (in atomic/element percent) in the range of Y=15–70% and Z=30–85%. The chalcogenide glasses of the invention have a 10,000 poise temperature of 400° C. and are resistant to crystallization when processed at high shear rates at their 10,000 poise temperature. The glasses can be used to make, among other items, molded telecommunication elements, lenses and infrared sensing devices.

    摘要: IR-transmitting alkaline earth selenogallo- and/or selenoindo-germanate glasses that are capable of hosting luminescent rare earth dopants. The relatively high Ga and/or In content of most compositions serves to eliminate the typical clustering tendency of rare earth dopants in chalcogenide glasses, resulting in improved luminescence.
