The nonradiative changeover prices follow the system WNR = W (0) exp(-alphap), in which p is the quantity of phonons matching the Power gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace rates is intricate https://richardy680zyy1.wikihearsay.com/user
