The nonradiative changeover premiums follow the system WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the Power gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence according to the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure prices is complicated https://josephf792dax1.win-blog.com/profile
