The nonradiative transition premiums follow the method WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the Strength gap. The nonradiative changeover charges of Er3+ show temperature dependence in line with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative leisure fees is https://tonya356kfy0.blogdal.com/profile
