The nonradiative transition premiums Keep to the formula WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Strength hole. The nonradiative transition costs of Er3+ show temperature dependence in line with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices is https://er-yb-yab-crystal07395.topbloghub.com/39480898/the-best-side-of-er-yb-yab-crystal
