Chalcogenide glasses for sensor application: A Review

Chalcogenide vitreous semiconductors are chemical compounds of chalcogen S, Se or Te atoms combined with some other elements of another group of the periodic table obtained with melt-quench. Chalcogenide glasses plays an important role in various technological fields where their properties are engaged in computer memories, photodetectors, telecommunications, chemical, and ionic sensors. These glasses have an excellent transmission in near and infrared spectral region. These glasses are used for preparing writing channel waveguides. A review of fabrication, structural and optical properties, applications generally for sensing is discussed in the present paper which can help the researchers to formulate their future research plan.
