The nonradiative transition charges Adhere to the system WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the energy hole. The nonradiative transition costs of Er3+ show temperature dependence according to the multiphonon peace concept. In Tm3+ the temperature dependence of nonradiative relaxation premiums is difficult https://everetty479xxv0.levitra-wiki.com/user
