Using infrared (IR) spectroscopic microscopy we studied resonant light scattering from gold nanorods prepared by electron beam lithography (EBL) as well as from cylindrical gold nanowires prepared by the template method. Rectangular nanorods with diameter in the 100 nm range act as resonant antennae showing significant antenna-like plasmon resonances similar to those of cylindrical nanowires wi...

© 2016 Journal of ophthalmic and Vision research | published by Wolters KluWer medKnoW Dear Editor, All types of welding produce ultraviolet (UV), visible, and infrared (IR) radiation at damaging levels.[1] Photokeratoconjunctivitis (welder's flash), pingueculum, pterygium, corneal opacity, and pigmentary macular deposits are common eye disorders among welders.[2-4] Use of protective eyewear wh...

Silicon nitride thin films play an important role in the realization of sensors, filters, and high-performance circuits. Estimates of the dielectric function in the far- and mid-IR regime are derived from the observed transmittance spectra for a commonly employed low-stress silicon nitride formulation. The experimental, modeling, and numerical methods used to extract the dielectric parameters w...

The paper is the first comprehensive study on alpha particle irradiation effects on four mid-IR materials: CaF2, BaF2, Al2O3 (sapphire) and ZnSe. The measurements of the optical spectral transmittance, spectral diffuse reflectance, radioluminescent emission, terahertz (THz) spectral response, transmittance, absorbance, refractive index, real and imaginary parts of the dielectric constant and TH...

IR sensor synchronizing active shutter glasses for three-dimensional high definition television (3D HDTV) were developed using a flexible liquid crystal (FLC) lens. The FLC lens was made on a polycarbonate (PC) substrate using conventional liquid crystal display (LCD) processes. The flexible liquid crystal lens displayed a maximum transmission of 32% and total response time of 2.56 ms. The tran...

LLE Review, Volume 101 35 Introduction and Motivation The development of optics for new applications is based on the use of materials that have the appropriate mechanical and optical properties. For infrared (IR) window and dome materials that protect imaging systems against damaging conditions, three main considerations are taken into account: material strength, thermal-shock resistance, and o...

Infrared (IR) spectroscopy is an old analytical technique that has been widely utilized as a routine tool by the fats and oils industry . The measurement of physicochemical properties by FT-IR spectroscopy, not only provide the benefit of rapid analysis but also avoid dangers associated with reagents used in the traditional chemical method. Mid IR spectra have been used to characterize edible o...

Iron containing CeVO4 films were prepared using the sol–gel method. The crystalline structure of powders and films with Fe/Ce/V ratios of 0.1:1:1, 0.3:1:1 and 0.5:1:1 were investigated by X-ray diffraction (XRD) and infrared (IR) spectroscopy. XRD revealed the predominance of a CeVO4-W (wakefieldite) crystalline phase with a small amount of monoclinic CeVO4, CeO2 and Fe2O3. Ex situ IR absorbanc...

Sweet chestnut (Castanea sativa Mill.) belongs to the family Fagaceae and sub family Castaneoideae. Bioactive components such as tannins are present in sweet chestnut in high proportion giving astringent bitter taste and reducing their palatability. Roasting reduces the anti-nutritional factors in chestnut. This study was conducted to compare the effects of pan and microwave roasting on physico...

Multilayer coating structure comprising a copper (Cu) layer sandwiched between titanium dioxide (TiO2) were demonstrated as a transparent heat reflecting (THR) coating on glass for energy-saving window application. The main highlight is the utilization of Cu, a low-cost material, in-lieu of silver which is widely used in current commercial heat reflecting coating on glass. Color tunable transpa...
