The nonradiative transition charges Adhere to the method WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy gap. The nonradiative changeover premiums of Er3+ show temperature dependence per the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is sophisticated from https://erickegecy.tokka-blog.com/33535303/the-basic-principles-of-er-yb-yab-crystal
