The nonradiative transition premiums follow the system WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Electricity hole. The nonradiative transition charges of Er3+ show temperature dependence in keeping with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative relaxation costs is complicated https://frankq135nli5.madmouseblog.com/13607995/the-5-second-trick-for-er-yb-yab-crystal
