摘要	Nanocrystalline ZrO(2) fine powders were prepared via the one-pot reaction followed by annealing from 700 to 1100 degrees C in air. It is believed that generation of excess oxygen vacancies within nanocrystalline ZrO(2) is primarily responsible for room-temperature tetragonal phase stabilization below a critical size, and the phase transformation from tetragonal to monoclinic ZrO(2) happened in the annealing process. Luminescent properties of ZrO(2) were greatly affected by oxygen vacancies in the phase transition process. Two bands centered at 350 and 470 nm were observed in tetragonal ZrO(2). The electrons trapped by oxygen vacancies creating F centers recombined with holes yielding the 350 nm luminescence. Temporal decay of the 470 nm luminescence is due to the detrapping of electrons to the Ti(3+) luminescence centers. Elevated temperature accelerated the phase transformation to monoclinic ZrO(2) and decreased the oxygen vacancy concentration, resulting in a decrease of the 350 urn emission and enhancement of the 470 nm phosphorescence.
