ER:YB:YAB CRYSTAL CAN BE FUN FOR ANYONE

The nonradiative transition rates Stick to the formulation WNR = W (0) exp(-alphap), where by p is the number of phonons matching the Vitality hole. The nonradiative transition prices of Er3+ exhibit temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation costs is intricate fro
