The nonradiative changeover prices Adhere to the formula WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Electricity gap. The nonradiative changeover costs of Er3+ show temperature dependence in step with the multiphonon leisure concept. In Tm3+ the temperature dependence of nonradiative peace rates is https://erybyabcrystal17395.jts-blog.com/32158066/5-simple-techniques-for-er-yb-yab-crystal
