Single-Particle Emission Spectroscopy Resolves d-Hole Relaxation in Copper Nanocubes

Detection of Bioaerosols using Single Particle Thermal Emission Spectroscopy

Localized surface plasmon resonance spectroscopy of single silver nanocubes.

In this work, we use dark-field microscopy to observe a new plasmon resonance effect for a single silver nanocube in which the plasmon line shape has two distinct peaks when the particles are located on a glass substrate. The dependence of the resonance on nanocube size and shape is characterized, and it is found that the bluer peak has a higher figure of merit for chemical sensing applications...

Black hole particle emission in higher-dimensional spacetimes.

In models with extra dimensions, a black hole evaporates both in the bulk and on the visible brane, where standard model fields live. The exact emissivities of each particle species are needed to determine how the black hole decay proceeds. We compute and discuss the absorption cross sections, the relative emissivities, and the total power output of all known fields in the evaporation phase. Gr...

Gold nanoparticles with tipped surface structures as substrates for single-particle surface-enhanced Raman spectroscopy: concave nanocubes, nanotrisoctahedra, and nanostars.

We demonstrate that Au nanoparticles with tipped surface structures, such as concave nanocubes, nanotrisoctahedra, and nanostars, possess size-dependent tunable plasmon resonances and intense near-field enhancements exploitable for single-particle surface-enhanced Raman spectroscopy (spSERS) under near-infrared excitation. We report a robust seed-mediated growth method for the selective fabrica...

Application of infrared emission spectroscopy to the thermal transition of indium hydroxide to indium oxide nanocubes.

Cubic indium hydroxide nanomaterials were obtained by a low-temperature soft-chemical method without any surfactants. The transition of nano-cubic indium hydroxide to cubic indium oxide during dehydroxylation has been studied by infrared emission spectroscopy. The spectra are related to the structure of the materials and the changes in the structure upon thermal treatment. The infrared absorpti...
