Abstract
This paper describes the results of an investigation of energy transfers between Er3+ and Tm3+ ions in cadmium fluoride crystals. Four non-radiative transfers which play an important role in the infrared conversion processes are presented. For the first time, we report Er3+→Tm3+→Er3+ transfers which explain how the Tm3+ acts as the sensitizer of the red fluorescence of Er3+. The study of energy transfer by measurements of the anti-Stokes fluorescence intensity is shown to be a useful method to clarify the excitation mechanisms of rare-earth ions.
