The nonradiative changeover rates follow the formulation WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the Power gap. The nonradiative transition prices of Er3+ exhibit temperature dependence in step with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative relaxation charges is https://scottt257pok3.tnpwiki.com/user
