The nonradiative transition premiums Keep to the formula WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Strength gap. The nonradiative changeover costs of Er3+ show temperature dependence in keeping with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation costs is https://englandh702dca2.blogpayz.com/profile
