摘要：

Porous alumina membranes with ordered pore arrays were prepared electrochemically from Al metal in C2H2O4 or H2SO4. Photoluminescence (PL) measurements show that a blue PL band occurs in the wavelength range of 400-600 nm. This band originates from singly ionized oxygen vacancies (F+ centers) in porous alumina membranes. Tentative reasons for the changes in intensity and peak position of the PL band with increasing heat-treatment temperature are discussed. (C) 1999 American Institute of Physics.
