Wavelength: µm (0.667 – 200) Complex refractive index (n+ik) TUNGSTEN OXIDE, WO 3. CAS 1314-35-8 Melting Point (0 C) 1473 Evaporation Temperature (0 C) 1460 Density (g/cm 3) 7.1 Refractive Index: 1.7 Tungsten trioxide (WO 3) is the most widely used material for the active layer of electrochromic devices. Knowledge of the complex refractive index over the range of coloration states is required for device design. 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.
By varying deposition parameters, three main types of WO3 film exhibiting different optical properties form. These are blue, gray, and colorless films. The samples are characterized optically and morphologically.

The extinction coefficient of the film showed a large value at 1450 nm, which corresponds to the minimum of the transmittance spectrum of the film.

The films (2000–23000 Å thick) were formed by rf sputtering from a metallic tungsten target under a constant operating pressure ranging from 5×10−3 to 6×10−2 Torr using a mixture of Ar‐4–50% O2. 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. It is revealed that gas induced free carrier absorption is the dominant mechanism for the refractive index modulation. Tungsten microcavity light sources and tungsten cluster light sources have interested us as light sources for next-generation having high luminous efficacy and long lifetime. The complex refractive index of tungsten requires the operating temperatures from 2000 K to 6500 K to evaluate the luminous efficacy and lifetime. Little is, known however, about the complex index of tungsten at such high Tungsten, also known as wolfram. For a typical sample of W the refractive index and extinction coefficient at 632.8 nm are 3.63739 and 2.916877. Below are files of complete refractive index and extinction coefficients.

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.
