The nonradiative transition premiums Adhere to the system WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Electrical power gap. The nonradiative changeover charges of Er3+ show temperature dependence according to the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative peace charges is difficul
