The nonradiative changeover charges follow the formula WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Electrical power gap. The nonradiative transition rates of Er3+ exhibit temperature dependence in line with the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative leisure charges https://greatl913gec3.robhasawiki.com/user
