                         conventional spectroscopy. The experimental data are 
                         quantitatively analyzed in terms of the energy transfer among the 
                         Yb3+ and Er3+ ions. The energy transfer rate by dipole-quadrupole 
                         mechanism was inferred to be larger than by dipole-dipole 
                         mechanism. Using the Dexter model of energy transfer, the 
                         microscopic parameters of energy transfer by dipole-dipole 
                         mechanism were calculated. It was found that the Yb3+--> Er3+ 
                         energy transfer constant is 2.6 times greater than the back-energy 
                         transfer.",
