λ (nm) Tungsten oxide films were prepared by sol-gel and sputtering processes. The refractive index of the film increased with increasing wavelength in the visible and infrared region. The extinction coefficient ofthe film showed a large value at 1450 nm, 2018-01-26 The concept is demonstrated by tungsten trioxide inverse opal structure as optical transducer material for hydrogen sensing. The sensing behavior is analyzed in a temperature range from room temperature to 500 °C and in a wide hydrogen concentration range (3000 ppm to 10%). The sensing mechanism is mainly the refractive index [Show full abstract] The refractive index of the films was found to be in the range of 1.7–2.3 and the optical band gap energy, Eog, estimated from the absorption analysis, was in the range of 2 With a series of tungsten oxide photonic crystals the hydrogen induced strong refractive index dispersion of the oxide is reconstructed by analyzing its optical response.

Tungsten oxide refractive index

Optical constants of WO 3 over the whole solar spectrum were determined as a function of injected charge. WO3 | Tungsten oxide basic knowledge Last modified; May 5, 2010 WO3 has a refractive index near 2.2 at 550 nm and a transmittance range from below 400 nm into the IR region. It is a candidate high-index material for the VIS region. With a series of tungsten oxide photonic crystals the hydrogen induced strong refractive index dispersion of the oxide is reconstructed by analyzing its optical response.

Tungsten oxide refractive index

519. References. 527. Index.

The sensing mechanism is mainly the refractive index change resulting from hydrogen intercalation in tungsten trioxide, but the back reaction has also impact on the optical properties The dependence of refractive index as well as extinction coefficient on wavelength was also reported. The energy gap was calculated and is located around 3.25 eV. Tungsten oxide films of 240 are: refractive index, growth rate, resistivity, and stoichiometry.

Tungsten oxide refractive index





La 2 O 3 is used to make optical glasses, to which this oxide confers increased density, refractive index, and hardness. Together with oxides of tungsten, tantalum, and thorium, La 2 O 3 improves the resistance of the glass to attack by alkali. La 2 O 3 is an ingredient for the manufacture of piezoelectric and thermoelectric materials.

The samples are characterized optically and morphologically. Blue-colored samples exhibit a broad Title: Microsoft Word - ISCA-RJCS-2011-193 Done.docx Author: Admin Created Date: 1/17/2012 6:39:26 PM Both types of tungsten oxide films showed low absorption and high transparency in the visible range. As expected, we found that the film density, and hence the refractive index and extinction coefficient, depended on coating solution chemistry, hydration, and densification procedures.
