THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative transition prices follow the system WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Electricity hole. The nonradiative changeover costs of Er3+ show temperature dependence per the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is complicated through the ex
