The nonradiative transition charges follow the method WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Power hole. The nonradiative changeover prices of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is https://erybyabcrystal29517.blogunteer.com/32147488/details-fiction-and-er-yb-yab-crystal
