The nonradiative changeover costs follow the method WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Electricity gap. The nonradiative transition fees of Er3+ exhibit temperature dependence according to the multiphonon peace concept. In Tm3+ the temperature dependence of nonradiative rest charges is intricate https://jacky479xvs9.wannawiki.com/user
