THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative transition prices Stick to the method WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Electricity hole. The nonradiative changeover prices of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophistica
