Facile synthesis of gold coated copper(II) hydroxide pine-needle-like micro/nanostructures for surface-enhanced Raman scattering

The growth simulation of pine-needle like structure with diffusion-limited aggregation and oriented attachment

“…6c, only one needle traps almost all the late particles. However, the realistic pine-needle like structure has no the very prominent needle, [49][50][51][52] like the DLA and OA on a point. This is mainly because the particle density in real systems is so high that the growth rate becomes greater, rather than one by one.…”

“…This could be a quantitative understanding of how and why only a few needles grow during some preparations of pine-needle-like micro/nanostructures on plane. 51,52,67 Because of relatively low steric hindrance on the line and sphere, the growth of needles is divergent to all around. And more needles stand out in the cluster compared with that on plane.…”

“…It is in accordance with the actual characteristic of the report. [49][50][51][52] Furthermore, the distribution of particles was investigated. It should be noted that even though no surface with a basis of line (Fig.…”

“…As a novel morphology, pine-needle like micro/nano-structures is attractive prospect in various fields, such as solar cells, 36,37 capacitors, 38–40 catalysts 41–43 and sensors. 44–46 The formation of this 3D nano-architectures present likely spontaneously and radially growth from bases or templates including point, 47,48 line, 49,50 plane 51–53 and sphere. 54–57 This growth process could be considered an analogous aggregation combined with random movement and OA.…”

A Review of Chinese Raman Spectroscopy Research Over the Past Twenty Years

“…The LODs for Nile blue A and rhodamine 6 G were 5 × 10 −11 M and 1 × 10 −9 M, respectively. 183 Teng Qiu, also of Southeast University, has developed rolled-up Ag-SiO x , hyperbolic metamaterials, 184 gold coated Cu(II) hydroxide pine-needle-like micro-nanostructures, 185 and tunable silver nanocap superlattice arrays for SERS research. 186…”
