Open AccessNaturally inspired SERS substrates fabricated by photocatalytically depositing silver nanoparticles on cicada wings
Densely stacked Ag nanoparticles with an average diameter of 199 nm were effectively deposited on TiO2-coated cicada wings (Ag/TiO2-coated wings) from a water-ethanol solution of AgNO3 using ultraviolet light irr...

Femtosecond optical nonlinearities of Au/TiO2 thin films prepared by a sputtering method
A multitarget sputtering method was applied to embed Au nanoparticles in TiO2 thin films (Au/TiO2 films) with a high concentration of Au particles (19–41 at%). The absolute values of imaginary part of the third-o...

Localized surface plasmon resonance sensing properties of photocatalytically prepared Ag/TiO2 films
Photocatalytic deposition of Ag nanoparticles from a mixed aqueous solution of AgNO3 and polyvinylpyrrolidone (PVP) onto TiO2 film supported on indium-tin oxide-coated glass slide (Ag/TiO2 film) was carried out b...
