Investigators from University of Latvia Release New Data on Plasmonics

May 27, 2014

By a News Reporter-Staff News Editor at Physics Week -- New research on Plasmonics is the subject of a report. According to news reporting originating in Riga, Latvia, by VerticalNews journalists, research stated, "We address the optical properties of dense disordered yet well-separated metal nanoparticle arrays produced by physical vapor deposition through anodized aluminum oxide membrane masks."

The news reporters obtained a quote from the research from the University of Latvia, "Using variations in synthesis parameters, the particle diameters vary from 14 to 50 nm and average center separation from 45 to 112 nm. Ag nanoparticle arrays with no long-range periodicity exhibit apparently random formation of high-intensity depolarized regions relative to orientation of incident electric field."

According to the news reporters, the research concluded: "We analyze this behavior numerically using coupled dipole model and explain the contrast formation in recorded scattering images."
