Abstract
The authors developed plasmonic structures of zinc (Zn) and zinc oxide (ZnO) on the surface of a tapered optical fiber using optical tweezing. The powdered Zn or ZnO was added to gold nanorods (GNRs) solution and sonicated before tweezing. The concentration of the mixture was 0.5 µg/µl. The GNRs were present in the cetyltrimethylammonium bromide (CTAB) solution. The authors investigated the plasmonic structures and explored the effect of the tweezing conditions on the distribution of the Zn or ZnO on the tapered fiber surface.
