Local structure and its effect on the oscillator strengths and emission properties of Ho3+ in chalcohalide glasses
Source abstract
Abstract
Abstract The formation of structural units in Ge–Ga–S glass with CsBr addition and its effect on the optical band gap and several spectroscopic properties of Ho 3+ were investigated. The optical band gap of the host glasses and the oscillator strengths of Ho 3+ absorption decreased sharply when the ratio of CsBr/Ga became close to unity. These property changes were associated with the formation of structural units of [GaS 3/2 Br] − and they have a crucial effect on the changes of the local structure around Ho 3+ ions. The local structure was not sensitive to the As or Br addition but was critically dependent on the concentration of CsBr.
