RUMORED BUZZ ON ER:YB:YAB CRYSTAL

The nonradiative transition costs Stick to the method WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electrical power gap. The nonradiative transition premiums of Er3+ show temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticated from
