The nonradiative changeover charges Stick to the system WNR = W (0) exp(-alphap), where by p is the volume of phonons matching the Electricity gap. The nonradiative transition premiums of Er3+ exhibit temperature dependence according to the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative relaxation rates is https://hatshepsutr381gko8.fliplife-wiki.com/user
