The nonradiative transition charges Adhere to the formula WNR = W (0) exp(-alphap), where p is the number of phonons matching the energy gap. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest premiums is https://gregoryjymzk.wssblogs.com/34736945/er-yb-yab-crystal-an-overview
