The nonradiative transition costs follow the system WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Electrical power hole. The nonradiative transition costs of Er3+ show temperature dependence in line with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative relaxation charges is https://er-yb-yab-crystal42849.therainblog.com/32054187/5-easy-facts-about-er-yb-yab-crystal-described
