Tunable optical excitations in gold nanorings

Not Accessible

Your library or personal account may give you access

Abstract

The optical response of gold nanorings is measured and analyzed theoretically. Compared to gold disks, nanorings exhibit a red-shifted surface plasmon that can be tuned by varying the ratio between ring thickness and radius.
