Abstract
Abstract Chalcogenide glasses are attracting interest nowadays due to their various technological applications like telecommunications, computer memories, chemical, and ionic sensors, writing channel waveguides and photo-detectors. These glasses possess large transmission in middle, far and near spectral region. Se–Te alloys have created extreme interest due to their greater hardness, lower aging effect, higher photosensitivity, and higher crystallization temperature as compared with amorphous Se. A review of fabrication, optical properties, characterization techniques, doping effect of various elements on Se–Te compounds and also their optoelectronic applications are discussed in the present paper which can help the researchers to expedite their research work in the field of chalcogenide glasses.
