Color Changes in Ag Nanoparticle Aggregates Placed in Various Environments: Their Application to Air Monitoring
Fresh Ag nanoparticles (NPs) dispersed on a transparent SiO<sub>2</sub> exhibit an intense optical extinction band originating in localized surface plasmon resonance (LSPR) in the visible range. The intensity of the LSPR band weakened when the Ag NPs was stored in ambient air for two wee...
