Abstract :
The photoluminescence of anodically prepared ZrO2 films was investigated. Morphological and microstructural analyses reveal an oxide surface covered by a high distribution of blisters and the major crystallographic structure is the monoclinic phase with small quantities of tetragonal phase. The photoluminescence reveals a broad emission band in the range between 350 and 650 nm. It was proposed that the photoluminescence mechanism is originated from the emission of a recombination center related to defects (oxygen vacancies) formed during Zr anodization.
