The nonradiative transition prices Adhere to the formula WNR = W (0) exp(-alphap), in which p is the number of phonons matching the Strength hole. The nonradiative changeover costs of Er3+ show temperature dependence consistent with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative relaxation prices is https://manuellttyx.fireblogz.com/64424422/er-yb-yab-crystal-can-be-fun-for-anyone
