Design of nanoscale structures with desired nanophotonic properties are key tasks for nanooptics and nanophotonics. Here, the correlative relationship between local nanoparticle geometries their plasmonic responses is established using encoder-decoder neural networks. In im2spec network, particle spectra via encoding observed to a small number latent variables subsequently decoding into spectra...

Nanoparticle superlattices are periodic arrays of nanoscale inorganic building blocks including metal nanoparticles, quantum dots and magnetic nanoparticles. Such assemblies can exhibit exciting new collective properties different from those of individual nanoparticle or corresponding bulk materials. However, fabrication of nanoparticle superlattices is nontrivial because nanoparticles are noto...

We classify the strategies for colloidal assembly and review the diverse potential applications of microand nanoparticle structures in materials and device prototypes. The useful properties of the particle assemblies, such as high surface-to-volume ratio, periodicity at mesoscale, large packing density, and long-range ordering, can be harnessed in optical, electronic, and biosensing devices. We...

Carbon nanotube (CNT) and metal nanoparticle (NP) assemblies are conjugated nanosystems with potential applications in catalysis, sensing, and light harvesting. Due to poor solubility of CNTs, previously reported synthetic approaches are limited to large multi-walled CNTs, bundles of single-walled CNTs (SWNTs), or surface-bound CNTs. Here we report a solution-phase synthesis of SWNT-metal NP as...

Synthesis of monodisperse iron-platinum (FePt) nanoparticles by reduction of platinum acetylacetonate and decomposition of iron pentacarbonyl in the presence of oleic acid and oleyl amine stabilizers is reported. The FePt particle composition is readily controlled, and the size is tunable from 3- to 10-nanometer diameter with a standard deviation of less than 5%. These nanoparticles self-assemb...

DNA-functionalized nanoparticles, including plasmonic nanoparticles, can be assembled into a wide range of crystalline arrays via synthetically programmable DNA hybridization interactions. Here we demonstrate that such assemblies can be grown epitaxially on lithographically patterned templates, eliminating grain boundaries and enabling fine control over orientation and size of assemblies up to ...

This paper describes a simulation model of nanoparticle assemblies formed by spray deposition. The simulation deposits nanoparticles via a semi-mechanistic process, which in spite of its simplicity generates morphologies of considerable complexity. The experiments reveal several relationships between nanoparticle parameters such as their relative proportions in mixtures, and resulting surface p...
