The nonradiative transition costs Stick to the components WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electrical power gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence per the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative leisure fees is complex with the existen
