We investigate the spectral relationships between electromagnetic (EM) enhancement and surface-enhanced resonant Raman scattering (SERRS) with fluorescence (SEF), which is observed as background emission of SERRS, in context light–matter interactions subradiant plasmons molecular excitons, using single silver nanoparticle dimers a model system. focus on lowest-energy (superradiant) plasmon far-...

Tuning optical properties of plasmonic nanostructures, including their absorption, scattering, and local-field distribution is great interest for various applications that rely on energy regulated by effects. Conventional nanostructures enhance light scattering absorption simultaneously, leading to compromise either surface-enhanced spectroscopy or thermoplasmonic applications. In this paper, a...

Dielectric nanosphere arrays are considered as promising light-trapping designs with the capability of transforming the freely propagated sunlight into guided modes. This kinds of designs are especially beneficial to the ultrathin hydrogenated amorphous silicon (a-Si:H) solar cells due to the advantages of using lossless material and easily scalable assembly. In this paper, we demonstrate numer...

The appearance of a light composite $0^+$ scalar resonance in nearly conformal gauge-fermion theories motivates further study the low energy structure these theories. To this end, we present nonperturbative lattice calculation s-wave scattering Goldstone bosons maximal-isospin channel SU(3) gauge theory with $N_f=8$ light, degenerate flavors. phase shift is measured both for different values un...

Green nano pigments of Cr2O3 and CoCr2O4 were successfully prepared by polyol method followed by calcination at 770°C. The Cr2O3 and CoCr2O4 samples were characterized by X-ray diffraction XRD, scanning electron microscopy SEM, diffuse reflectance spectroscopy DRS, dynamic light scattering DLS, UV–Vis spectroscopy and CIE-Lab colorimetry methods. Dynamic light scattering analysis confirmed the f...
