The nonradiative transition premiums Stick to the method WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the energy hole. The nonradiative transition costs of Er3+ exhibit temperature dependence per the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative peace costs is challenging from https://erybyabcrystal96172.blogproducer.com/41914408/facts-about-er-yb-yab-crystal-revealed
