The nonradiative transition premiums Keep to the method WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the Electrical power gap. The nonradiative transition premiums of Er3+ exhibit temperature dependence in step with the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative relaxation https://grahame681ayw1.shivawiki.com/user
