The nonradiative changeover charges follow the method WNR = W (0) exp(-alphap), exactly where p is the amount of phonons matching the energy gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure fees is https://erybyabcrystal85626.tinyblogging.com/5-tips-about-er-yb-yab-crystal-you-can-use-today-78486779
