ER:YB:YAB CRYSTAL CAN BE FUN FOR ANYONE

The nonradiative transition prices Stick to the formulation WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Electricity gap. The nonradiative changeover charges of Er3+ show temperature dependence in step with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative peace fees is complex through
