A SIMPLE KEY FOR ER:YB:YAB CRYSTAL UNVEILED

The nonradiative transition charges Adhere to the formula WNR = W (0) exp(-alphap), wherever p is the quantity of phonons matching the Strength hole. The nonradiative transition fees of Er3+ show temperature dependence in line with the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative rest rates is sophisticated throug
