Abstract
The conditions of synthesis and luminescence characteristics of composites Al2O3:Cr3+/NaAl(MoO4)2:Cr3+ obtained from molybdate high-temperature solutions have been studied. The influence of the impurity Cr3+ ions on crystallization regions in the molten system Na-Al-Mo-O has been detected as a key factor of composite formation. The luminescence emission spectra of the composite exhibit two narrow lines at 692 nm (Al2O3:Cr3+) and 740.5 nm (NaAl(MoO4)2:Cr3+), which indicates that both components of the composite are doped with chromium.
