The nonradiative changeover costs Keep to the method WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power gap. The nonradiative transition charges of Er3+ show temperature dependence in line with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative relaxation https://stevey468vus9.blog-mall.com/profile
