The nonradiative transition rates Adhere to the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Vitality hole. The nonradiative transition charges 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-crystal37148.bloggazza.com/32354474/the-definitive-guide-to-er-yb-yab-crystal
