Abstract

Trace Ti doped nano-zirconia was prepared via the one-pot reaction, and its phase transition and luminescence properties were characterized. It is believed that generation of excess oxygen vacancies within the trace Ti doped ZrO 2 nanocrystalline is primarily responsible for the room temperature tetragonal phase stabilization below a critical size. Luminescent properties of ZrO2 are greatly affected by the oxygen vacancies in the phase transition process, leading to the enhancement of the 470 nm phosphorescence and the identical color long afterglow.
