The nonradiative transition charges follow the formula WNR = W (0) exp(-alphap), where p is the number of phonons matching the Electrical power hole. The nonradiative transition costs of Er3+ exhibit temperature dependence per the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative leisure prices is complicated via https://er-yb-yab-crystal30627.imblogs.net/82884202/helping-the-others-realize-the-advantages-of-er-yb-yab-crystal
