Tungsten-based glasses for photochromic, electrochromic, gas sensors, and related applications: A review

The present work focuses on reviewing the scientific literature on various types of tungsten-based glasses such as tungsten–phosphate, tungsten–tellurite, tungsten–borate glasses, tungsten–germinate, tungsten–antimonate, and non-traditional tungsten oxide-containing glasses. The glass formation, structure, thermal, some chemical, physical and characterization of materials are discussed. Tungsten-based glasses show a remarkable potential for many photochromic, electrochromic and gas sensing applications.
