Abstract

Zirconium dioxide nanoparticles were prepared by the microwave-driven hydrothermal synthesis at UNIPRESS, Warsaw. The study of annealing of ZrO2 nanocrystals in different surrounding atmosphere has been carried out and the luminescence has been measured. The experiment shown that one reason for the luminescence intensity dependence on temperature for ZrO2 nanocrystals is the change of oxygen content in nanocrystals. It is expected the ZrO2 nanocrystals might be used as a prospective material for optical oxygen pressure sensor.
