Metal oxide glass nanocomposites

Abstract Glass and glass nanocomposite materials have attracted considerable attention during the last few years due to their several important properties including: easy to prepare, used as sensors, batteries, etc., which make them curious and most attentive materials for researchers. In spite of these positive aspects, they have some disadvantages such as the electrode polarization effect in the low-frequency regime, role of dimensionality of ion motion in the electrical relaxation process, etc. Chalcogenide glasses consist of one or more chalcogens or Group 16 elements of the periodic table, i.e., sulfur, selenium, and tellurium but excluding oxygen, and they exhibit a semiconducting nature. Band gap of chalcogenide glasses are observed to be in between 1 and 3 eV, which make them different from oxide glassy systems with a large band gap.
