THE 5-SECOND TRICK FOR ER:YB:YAB CRYSTAL

The nonradiative transition premiums Stick to the formula WNR = W (0) exp(-alphap), where by p is the number of phonons matching the Vitality hole. The nonradiative transition charges of Er3+ show temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative leisure prices is intricate via
