The nonradiative changeover charges follow the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Power gap. The nonradiative transition premiums of Er3+ show temperature dependence in line with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative peace fees is https://thomasp887huh3.cosmicwiki.com/user
