Abstract
Excitation of the transition in a -doped fluoroindate glass at ∼588 nm results in efficient blue emission at ∼480 nm which is ascribed to the . The upconversion process is due to an energy transfer involving a pair of ions. The dynamical behavior of the anti-Stokes emission is described using a rate-equation model which allows one to obtain the energy-transfer rates involving the pair states which contribute to the upconversion process.
