The nonradiative transition prices Stick to the formula WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Power hole. The nonradiative changeover costs of Er3+ exhibit temperature dependence consistent with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative rest premiums is difficult https://er-yb-yab-crystal73951.suomiblog.com/er-yb-yab-crystal-an-overview-48729286
