The nonradiative changeover premiums follow the formula WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Electrical power hole. The nonradiative transition charges of Er3+ exhibit temperature dependence in line with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative rest costs is https://er-yb-yab-crystal41728.glifeblog.com/32134978/er-yb-yab-crystal-options
