Current methods for placing nano-sized semiconductors on metallic particles to utilize them in nano-lasing and nano-lithography lack precision or are too costly. Researchers in Japan have developed a method based on a hydrothermal synthesis reaction to locally and selectively synthesize zinc oxide in a plasmonic nanoantenna. They first made evident the role of localized surface plasmon resonances (LSPR) for achieving efficient heating of gold nanostructures. Then, by selectively addressing one of the LSPRs of a gold antenna, they demonstrated that localized zinc oxide formation at the targeted location of the antenna can be achieved due to the nanoscale confinement of the heat production. Further research could lead to the development of powerful nano-sized light sources, highly efficient photoelectric conversion devices, and photocatalysts and applications in semiconductor electronics and optical quantum information processing…read more.
