		<abstract>The 2.8-mu m emission of Er3+-doped low silica content calcium aluminate glasses sensitized by Yb3+ is investigated using 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.</abstract>
