The nonradiative transition costs follow the system WNR = W (0) exp(-alphap), in which 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 https://messiahfggea.dailyblogzz.com/33666092/5-simple-techniques-for-er-yb-yab-crystal
