Some luminescent properties of additively colored KBr · Ag crystals

  • Published:
Soviet Physics Journal Aims and scope

Abstract

The luminescent characteristics of additively colored KBr · Ag crystals are investigated. In particular, the decay of the phosphorescence, the flash of emission due to IR light in relation to the silver concentration, and the temperature quenching of the steady luminescence are discussed. It is shown that the investigated crystals have a complex system of shallow and deep traps. The thermal activation energy for nonradiative transitions in the B centers is found. It is concluded that the luminescence is produced by an electron-recombination mechanism.
