The significant role of the chemical environments of rare earths ions in controlling their radiative and nonradiative processes are exemplified in this study: The emission properties of rare earth ions ( Dy3+ or Tm3+ ) embedded in the strong covalent chalcogenide glass ( Ge and/or As containing sulphide glass) are dramatically enhanced upon the addition of very small amount of the Group III elements ( Ga or In ) and alkali halides ( CsBr or RbBr ). These compositional adjustments alter only the local structural environments of rare earth ions, while thermal stability of the modified glass is kept unaltered.
