ER:YB:YAB CRYSTAL FOR DUMMIES

The nonradiative transition premiums Stick to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy gap. The nonradiative changeover fees of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure rates is challenging b
