Abstract

Plasmonics in the deep-UV spectral range (λ=200–300nm) has been eagerly studied in the recent decade. In this range, Al has been considered as the only reliable, efficient metal supporting surface plasmon resonances (SPRs) while SPRs can’t occur in Au and Ag[1]. In the study that will be presented in this talk, we will introduce indium (In) as another choice of metal for plasmonics in the deep-UV[2]. As used to be the case for Au and Ag that together have contributed to development of plasmonics in the visible spectral range, In will contribute together with Al to development of the plasmonics in the deep-UV.
