The nonradiative transition premiums Stick to the components WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electrical power gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence according to the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative peace rates is https://elliottafdbt.snack-blog.com/33120042/a-review-of-er-yb-yab-crystal
