The nonradiative transition charges follow the method WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the Power hole. The nonradiative changeover prices of Er3+ exhibit temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace rates is challenging https://elliotkmkie.ezblogz.com/64758836/er-yb-yab-crystal-can-be-fun-for-anyone
