The composite phosphors SrAl2O4/Sr3Al2O6:Bi2O3/Bi2O4 synthesized by a solid-phase approach have been studied by means of X-ray diffraction, Raman spectroscopy, and optical spectroscopy methods. A redistribution of Bi3+ ions between two phases was observed by changes in crystal parameters, bond length, and vibrational frequencies on Raman spectra. A relationship between the structure of the host matrix and the optical characteristics of phosphors has been established.
