Mullite glass-ceramics were prepared with varying concentrations of Cr(III). The X-ray absorption, emission and EPR spectra reveal that the most defined crystals are formed at the lowest concentration of Cr(II1). The concentration quenching of the luminescence is small and the quantum efficiencies h
