Halide glasses and their optical properties

Abstract

The different families of halide glasses are considered by reference to the glass-forming ability of divalent, trivalent and quadrivalent halides. The passive optical behavior, such as that in the IR transmission range, the low-loss potentiality and scattering problems, is discussed as well as the active function of halide glasses considered as new matrices for rare-earth or transition-metal spectroscopy. Some other properdes such as electrical or magnetic ones and those associated with purification, devitrification, chemical durability will be discussed.
