The nonradiative transition costs Stick to the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Vitality hole. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative rest premiums https://er-yb-yab-crystal41628.blogs100.com/33782061/getting-my-er-yb-yab-crystal-to-work
