Antimicrobial effects by silver–indium–tantalum oxide thin film in visible light

This study focuses on the antimicrobial effects in silver-indium-tantalum oxide (Ag–InTaO) thin films. A stack of alternated layers of Ag (7 nm), In2O3 (14 nm) and Ta2O5 (10 nm) was sequentially deposited by sputtering. Then this as-deposited stack of films was rapidly annealed at three selected...
