Abstract:
Glasses with compositions TexSe100−x (0x25 at.%), AsySe100−y (0y40 at.%) and As2TezSe98−z (0z25 at.%) were prepared. The effects of the additives As and Te on the crystallization behaviour and optical gaps of selenium were studied. The relationship between the above properties and the chemical bond nature of the glass constituents is discussed. Materials with long lifetime and high sensitivity can be obtained by the addition of certain amounts of As and Te into Se.
