LSPR effect of Aunanoparticles/ZnO nano-composite films.
Zinc oxide is an inorganic compound with
the formula ZnO. ZnO is a white powder that insoluble in water, and it is widely used
as an additive in numerous materials and products including rubbers, plastics,
ceramics, glass, cement, lubricants,paints, ointments, adhesives, sealants,
pigments, foods, batteries,
ferrites, fire retardants, and first-aid tapes. Although it occurs naturally as
the mineral zincite, most zinc oxide is produced
synthetically. Surface plasmon
resonance (SPR) is
the resonant oscillation of conduction electrons at the interface between
negative and positive permittivity material stimulated by incident light. SPR
is the basis of many standard tools for measuring adsorption of material onto planar metal (typically gold or silver) surfaces
or onto the surface of metal nanoparticles. The characteristic of Au nanoparticles has shown an obvious peak of absorbance located at 519 nm due to the
localized surface plasmon resonance (LSPR) effect.
