A spatially resolved microluminescence technique was used to measure the spatial distribution of emitted light and photon propagation into two different Pr3+ doped phosphate glasses. The photon diffusion length for specific wavelengths was measured. It was found that excited state re-absorption plays a crucial role in the propagation. Our results suggest that this microluminescence technique can be applied in the investigation of energy transfer processes in rare-earth doped systems.
