The nonradiative changeover prices follow the components WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electricity gap. The nonradiative transition fees of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure rates is challenging https://er-yb-yab-crystal30517.digiblogbox.com/57998624/a-secret-weapon-for-er-yb-yab-crystal
