The nonradiative changeover prices follow the system WNR = W (0) exp(-alphap), the place p is the quantity of phonons matching the energy gap. The nonradiative transition fees of Er3+ show temperature dependence in keeping with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest fees is https://messiahlbozl.prublogger.com/33925802/getting-my-er-yb-yab-crystal-to-work
