The nonradiative changeover costs Keep to the method WNR = W (0) exp(-alphap), in which p is the number of phonons matching the energy gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence in step with the multiphonon leisure concept. In Tm3+ the temperature dependence of nonradiative peace costs https://davyk924jhe4.wikibuysell.com/user
