The nonradiative transition costs follow the components WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electricity gap. The nonradiative transition fees of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure rates is challenging https://erybyabcrystal96284.blog-eye.com/33271099/the-smart-trick-of-er-yb-yab-crystal-that-nobody-is-discussing
