摘要	A facile synthetic route to synthesize the nanocrystalline zirconia particles via preparing polyzirconoxane with zirconium tetraalkoxide is reported, and the luminescent properties of the so-obtained ZrO(2):Ti nanophosphors are systematically investigated in this paper. The bluish-white photoluminescence and phosphorescence originating from the recombination of electrons trapped by anion vacancies and the holes created in the valence band, and the Ti(3+) ion substituting for Zr(4+) is assumed to be the luminescent center. The long afterglow from ZrO(2):Ti is attributed to the oxygen vacancies caused by the addition of Ti(3+) ions into ZrO(2) host. Compared with the bulk ZrO(2):Ti, the nanosized phosphors exhibit a longer persistent time because of the increased surface traps due to the large surface-to-volume ratio in the nanoparticles. This long persistent process can be elucidated by a simple possible mechanism. (C) 2008 The Electrochemical Society.
