The nonradiative changeover charges follow the formula WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Vitality hole. The nonradiative transition premiums of Er3+ exhibit temperature dependence in step with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative rest rates is https://tysonvgloy.bloggerbags.com/38401069/top-latest-five-er-yb-yab-crystal-urban-news
