The nonradiative transition costs Stick to the method WNR = W (0) exp(-alphap), where p is the amount of phonons matching the Power hole. The nonradiative changeover charges of Er3+ show temperature dependence in keeping with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative peace charges is https://marcosutrp.educationalimpactblog.com/54924661/er-yb-yab-crystal-an-overview
