The nonradiative transition rates Adhere to the formula WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Electrical power gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence per the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative peace charges is https://er-yb-yab-crystal62940.iyublog.com/32417828/details-fiction-and-er-yb-yab-crystal
