“…4(b) varies linearly with the change in RI, with a slope S = −25 • /RIU. Since ITO films may be functionalized with phosphonates [42], amines [43], zirconium complexes [44], carboxylic acids and thiols [45], DNA [46], and silanes [47], the results in Fig. 4 can be exploited, for example, in designing novel sensing/biosensing platforms to detect or monitor very small RI changes in the incident medium, with high precision.…”

Giant enhancement of the transverse magneto-optical Kerr effect through the coupling of ɛ -near-zero and surface plasmon polariton modes

We demonstrate a concept for the giant enhancement of the transverse magneto-optical Kerr effect (TMOKE), with amplitudes reaching the maximum theoretical values of ±1. The concept exploits the strong electromagnetic field localization in ε-near-zero metamaterials to excite surface plasmon resonances with no need of a prism or grating coupler, thus opening routes for magneto-optical devices amenable to miniaturization. A demonstration of the capability of the enhancement mechanism is presented in which giant TMOKE values can be used for sensing and biosensing.

Nanocrystalline materials such as Sn doped In 2 O 3 Indium Tin Oxide (ITO) were prepared by this Combustion technique and characterized. Presence of electronic centers in Nanocrystalline ITO is observed from Raman studies and the same has been confirmed by photoluminescence studies. The oxidation properties of ITO were studied by X-ray Diffract meter grain sizes are confirmed by structural studies. As against the expectation of oxide on individual Nano grains of In-Sn alloy, ITO Nano grains grew into faceted Nano grains on heat treatment in air and O 2 atmosphere. The growth of ITO under O 2 atmosphere showed pentagon symmetry. This Nanocrystalline ITO has been studied using Electron paramagnetic resonance (EPR) measurements. Structural studies by X-Ray Diffraction (XRD) showed the presence of dominant β phase with a minor quantity of α phase. In EPR, isotopic chemical shift peaks were observed and they are assigned to originate from the α, β phases of ITO and grain boundary component respectively. From this study, different atomic arrangements were identified in grain boundaries compared to the same within the grain in Nanocrystalline ITO. The atomic arrangement in the grain boundary seems to be somewhat different from regular periodic arrangement whereas inside the grain there is a good periodic arrangement of atoms. Above 5 mol%, Sn ions form correlated clusters, which lead to broadening. These EPR spectra were formed to contain two different components, one from the single isolated ions and the other from the clusters.

The formation of zirconium hexacyanoferrate(II) nanoparticles has been developed as a new resonance Rayleigh scattering (RRS) platform for the sensitive detection of trace amounts of dopamine (DA). The determination mechanism is based on dopamine reacting with hexacyanoferrate(III) ions to produce hexacyanoferrate(II) ions in acidic solution, which further react with zirconium ions to produce zirconium hexacyanoferrate(II) complexes. The zirconium hexacyanoferrate(II) complexes aggregate to form zirconium hexacyanoferrate(II) nanoparticles with an average diameter of about 50 nm. This aggregation can produce a strong RRS signal with the wavelength maximum at about 318 nm. This sensing system presented a good linear relationship between the increment of scattering intensity (DI RRS ) and the concentration of dopamine in the range of 0.03-1.3 mg mL À1 with a correlation coefficient of 0.9996 and a low detection limit (at a signal-to-noise ratio of 3) of 0.392 ng mL À1 . Furthermore, this reaction system has been applied successfully to the detection of DA in a pharmaceutical preparation, and the recoveries were between 100.78% and 104.43%.
