| The spectroscopy of pairs of rare-earth ions is demonstrated for Pr3+:CsCdBr3 For reasons of charge compensation only two definite types of Pr3+ pairs are formed independent of concentration. Only the pair with the Pr3+ ions as direct neighbors shows upconversion. The dynamics of this upconversion process is studied by time-resolved spectroscopy and discussed in the energy level schemes of the single ions, and the pair. |
