Abstract

Thin La2Mo2O9 (LMO) films were prepared using wet processing with acetylacetonates as starting materials. After acetylacetonates of La and Mo were dissolved into a mixture of 2-methoxyethanol and acetylacetone, the obtained precursor solution was coated onto Pyrex glass plates by spin coating. Transparent porous LMO thin film was obtained after vacuum ultraviolet light illumination and firing at 500 °C for 1 h in ambient air. The film exhibited antibacterial and antiviral activities that were almost equivalent to those of LMO powder against Escherichia coli, Staphylococcus aureus, bacteriophage Qβ, and bacteriophage Φ6.
