The nonradiative changeover charges Stick to the formula WNR = W (0) exp(-alphap), where by p is the volume of phonons matching the Vitality gap. The nonradiative transition charges of Er3+ exhibit temperature dependence in step with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative leisure premiums https://jaidenpvyzz.fare-blog.com/34965338/the-definitive-guide-to-er-yb-yab-crystal
