Description

General description: Selenium is a non-metallic p-type semiconductor and is commercially produced as a by-product in refining sulfide-bearing copper minerals. It has good photovoltaic and photoconductive properties and is extensively used in the electronics such as solar cells, light meters, and, photocells. It also finds application in the field of ceramics, pigments, metallurgy, agriculture, glasses, and lubricants.
Application: Selenium has been used as a starting material tosynthesize selenium nanoparticles.
