The nonradiative transition costs Adhere to the formulation WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power gap. The nonradiative changeover fees of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative peace https://er-yb-yab-crystal52849.mybloglicious.com/53644097/er-yb-yab-crystal-an-overview
