The nonradiative transition prices Adhere to the system WNR = W (0) exp(-alphap), where p is the number of phonons matching the energy hole. The nonradiative transition prices of Er3+ show temperature dependence consistent with the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative rest rates is sophisticated https://er-yb-yab-crystal40638.ambien-blog.com/39562275/the-best-side-of-er-yb-yab-crystal
