Abstract

Abstract: ZrO₂ nanoclusters embedded in polyviny lalcohol film was made using a chemical method. The TEM image, X-ray spectrum and optical absorbance for ZrO₂ nanoclusters were determined experimentally. The average particie size of ZrO₂ nanoclusters embedded in polyviny lalcohol film is about 7.0nm. The band-gap of ZrO₂ nanoclusters determined at the room temperature absorbance curve is 3.024 eV.

Key words: ZrO₂, nanoclusters
