The nonradiative transition costs follow the method WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Electrical power gap. The nonradiative transition premiums of Er3+ exhibit temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest premiums is complex with https://erybyabcrystal18416.theisblog.com/33343354/5-easy-facts-about-er-yb-yab-crystal-described
