• Resumen

  • Optical absorption and emission spectra are presented for Sm3+ ions in ZnF2-CdF2 based glasses. The measured oscillator strengths and radiative rates for several transitions are compared with calculated values. The interaction between 1ons of Sm3+ has been investigated. The decay curves become nonexponential when the Sm3+ concentration is larger than 0.1 mol%. It can be explained by cross relaxation between Sm3+ ions.
