The nonradiative changeover charges Stick to the formulation WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Electricity gap. The nonradiative changeover premiums of Er3+ exhibit temperature dependence per the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative rest costs is difficult through https://louislrxff.qodsblog.com/34827728/the-5-second-trick-for-er-yb-yab-crystal
