The nonradiative changeover rates follow the components WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Electricity hole. The nonradiative transition costs of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is intricate https://traviscdcaw.smblogsites.com/33187882/the-best-side-of-er-yb-yab-crystal
