The nonradiative transition costs Stick to the formulation WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Electricity gap. The nonradiative transition charges of Er3+ exhibit temperature dependence consistent with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative rest costs is intricate https://edgarbfgeb.blog-eye.com/33407374/a-review-of-er-yb-yab-crystal
