THE GREATEST GUIDE TO ER:YB:YAB CRYSTAL

The nonradiative changeover charges follow the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Vitality hole. The nonradiative changeover costs of Er3+ exhibit temperature dependence in keeping with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative leisure prices is sophisticated with th
