Scarcity of oxygen is regarded as the reason for the growth of the small diameter α-Al2O3 nanowires at relatively low temperature. The product was characterized by field emission scanning electron microscopy, high-resolution transmission electron microscopy and photoluminescence. The Oxygen vacancies in the nanowires lead to the strong photoluminescence in the wavelength range of 400–700 nm with its peak at 527 nm.
