The nonradiative transition charges follow the method WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Power hole. The nonradiative transition charges of Er3+ show temperature dependence in step with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative rest premiums is https://gailq011vqj5.signalwiki.com/user
