The nonradiative changeover costs Stick to the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Power hole. The nonradiative changeover prices of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices is https://er-yb-yab-crystal41628.blogs100.com/33782061/getting-my-er-yb-yab-crystal-to-work
