The nonradiative transition charges follow the formulation WNR = W (0) exp(-alphap), exactly where p is the number of phonons matching the Electricity hole. The nonradiative transition charges of Er3+ show temperature dependence in step with the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative leisure fees is https://elliottzbaxt.idblogz.com/33809437/what-does-er-yb-yab-crystal-mean
