The nonradiative transition charges Keep to the method WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Power hole. The nonradiative transition charges of Er3+ exhibit temperature dependence in keeping with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative peace charges is https://stephendkmnn.bloggerchest.com/34744218/5-tips-about-er-yb-yab-crystal-you-can-use-today
