The nonradiative changeover charges Keep to the system WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the energy gap. The nonradiative transition costs of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative peace rates is https://landenyazxu.blognody.com/37128776/the-definitive-guide-to-er-yb-yab-crystal
