The nonradiative transition rates Keep to the formula WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Electrical power hole. The nonradiative transition costs of Er3+ show temperature dependence per the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative peace prices is https://elliottabbzw.articlesblogger.com/55694626/the-definitive-guide-to-er-yb-yab-crystal
