| Abstract: | The widely used energy transfer theory is a foundation ofluminescence, in which the rates of Stokes and anti-Stokes processeshave the same calculation formula. An improvement on the anti-Stokesenergy transfer to explain the fluorescence intensity reversalbetween the red and green fluorescence of Er(0.5)Yb(9.5):FOV is reportedin the present article. The range of the intensity reversalvarSigma was measured to be 877. Dynamic processes for 16levels were simulated. A coefficient, the improvement factor of theintensity ratio of Stokes to anti-Stokes processes in quantumRaman theory compared to classical Raman theory, is introducedto successfully describe the anti-Stokes energy transfer. A newmethod to calculate the distance between the rare earth ions, whichis critical for the energy transfer calculation, is proposed. Thevalidity of these important improvements is also proved byexperiment. |
