The preparation and modification of crystal structures in cryogenic environments with conventional methods is challenging, but it is essential for the development of composite materials, energy savings, and future human...

Plasmonic Au–Cu nanostructures: Synthesis and applications

“…Due to the advantages of Au–Cu plasmonic nanoparticles with tunable composition and spatial distribution, more plasmonic modes of Au–Cu plasmonic nanoparticles can be generated ( Li et al, 2010 ; Toscano et al, 2015 ; Zhuo et al, 2019 ). A wide range of applications have been reported in the fields of plasmon-enhanced electrocatalysis, surface-enhanced spectroscopy, phototherapy, and photocatalysis ( Chen et al, 2019 ; Mi et al, 2019 ; Zhang B. et al, 2022 ; Zhang C. et al, 2022 ; Chen et al, 2022 ). In the following sections, different applications of Au–Cu nanostructures are presented and discussed in detail.…”

“…It has been possible to prepare a variety of bimetallic nanostructures by using several different methods ( Feng et al, 2012 ; Lee et al, 2014 ; Zheng et al, 2020 ; Zhou L. et al, 2021 ; Zhou M. et al, 2021 ; Feng et al, 2021 ; Jiang et al, 2021 ; Skrabalak, 2021 ; Yang et al, 2021 ; Lee et al, 2022 ). Cu and Au nanostructures are excellent materials for applications in catalysis and plasmonic ( Zhang et al, 2019 ; Mi et al, 2021a ; Xin et al, 2021 ; Zhang B. et al, 2022 ; Lin et al, 2022 ). Cu nanostructures, which are valuable plasmonic materials in the visible to near-infrared region, have contributed to the development of applications in photonics, sensing, heterogeneous catalysts and imaging ( Gawande et al, 2016 ; Lee D. W. et al, 2021 ; Medvedeva et al, 2021 ).…”

Surface plasmon assisted preparation of X1-type Y2SiO5:Eu3+-Au luminescent crystals

“…26,27 As for Au/Ag nanoparticles (NPs), when the frequency of incident light approaches the frequency of collective electron oscillation, a localized surface plasmon resonance (LSPR) is usually excited, and leads to particularly intense local heat near the particle during LSPR relaxation. [28][29][30] This efficient energy conversion known as the plasmonic photothermal effect has been applied in photothermal therapy, 31,32 solar vapor generation, 33 seawater desalination, 34 rapid transformation of nanocrystals even at a low temperature (11 K), 35 etc. These various advances show unique advantages and practical value of the plasmonic photothermal effect.…”
