The nonradiative changeover prices follow the formula WNR = W (0) exp(-alphap), the place p is the number of phonons matching the energy hole. The nonradiative transition rates of Er3+ exhibit temperature dependence in keeping with the multiphonon peace concept. In Tm3+ the temperature dependence of nonradiative relaxation prices is https://nielsonb580yyv0.wikidirective.com/user
