Abstract
This paper presents results on the synthesis, phase composition, and optical properties of Al5O6N aluminum oxynitride doped with Fe ions in a broad concentration range: from 0.01 to 5.0 at % (relative to aluminum). All of the samples, prepared by firing mixtures of Al2O3, AlN, and Fe2O3 at a temperature of 1750°C in flowing nitrogen, consisted of almost phase-pure γ-AlON, with small amounts of aluminum nitride and unidentified phases. The band gap Eg of AlON:Fe depends on Fe concentration and ranges from 5.76 to 5.88 eV. We have identified AlON:Fe luminescence due to native defects and extrinsic emission centers and measured the luminescence intensity of emission bands as a function of Fe concentration in AlON. The presence of Fe in AlON leads to an increase in optical absorption and a decrease in intrinsic luminescence intensity in the material.
期刊介绍：
Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
