The nonradiative transition charges follow the method WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Power hole. The nonradiative changeover prices of Er3+ show temperature dependence in line with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticated https://juliusqgser.bloggerswise.com/42277015/the-ultimate-guide-to-er-yb-yab-crystal
