The nonradiative changeover costs Stick to the method WNR = W (0) exp(-alphap), where p is the number of phonons matching the Electrical power hole. The nonradiative transition premiums of Er3+ show temperature dependence in line with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative rest premiums https://erybyabcrystal74061.ampblogs.com/the-greatest-guide-to-er-yb-yab-crystal-69856208
