“…The protocol can be trivially extended to various shapes of Au nanostructures as cores, such as Au nanobipyramids, suggesting the generality of the site-selective overgrowth method ( Figures 3A–C ). Similarly, our group designed a new jellyfish-like Au–Cu Janus nanostructure ( Figure 3D ) ( Mi et al, 2022 ). A twin defect and stacking fault were found to exist at the twinned Au nanotips, which led to Cu atoms being deposited on the twinned nanotip.…”

“…The reason was explained by the enhancement of the local electromagnetic field intensity. Recently, Au–Cu nanostructures have been employed to enhance the luminescence of Yb 3+ /Er 3+ -doped nanoparticles ( Mi et al, 2022 ). The plasmonic Au–Cu Janus nanojellyfish showed two LSPR peaks, which coupled the emission and excitation of the light wavelength of the Yb 3+ /Er 3+ -doped nanoparticles.…”

Plasmonic Au–Cu nanostructures composed of Au and Cu metals, have demonstrated advantages over their monolithic counterparts, which have recently attracted considerable attention. Au–Cu nanostructures are currently used in various research fields, including catalysis, light harvesting, optoelectronics, and biotechnologies. Herein, recent developments in Au–Cu nanostructures are summarized. The development of three types of Au–Cu nanostructures is reviewed, including alloys, core-shell structures, and Janus structures. Afterwards, we discuss the peculiar plasmonic properties of Au–Cu nanostructures as well as their potential applications. The excellent properties of Au–Cu nanostructures enable applications in catalysis, plasmon-enhanced spectroscopy, photothermal conversion and therapy. Lastly, we present our thoughts on the current status and future prospects of the Au–Cu nanostructures research field. This review is intended to contribute to the development of fabrication strategies and applications relating to Au–Cu nanostructures.

“…[25][26][27] As a near-field enhancement technique, LSPR can boost the upconversion intensity by increasing the light absorption or improving the radiative decay rate when the resonance band is spectrally overlapped with the photoexcitation or fluorescence wavelength. [28][29][30][31] Since both the PBG and LSPR effects can enhance the upconversion emission by enlarging the local electromagnetic field, the combination of both is expected to cooperatively improve the intensity of the local electromagnetic field for high upconversion quantum efficiency. Although the coupling of the PBG and LSPR effects also has been researched to result in a remarkable increase in the upconversion emission of rare-earth upconversion materials, [32][33][34] the enhanced upconversion emission intensity is far from real applications due to its low intrinsic quantum efficiency.…”
