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.

Simulations show a 24% improvement in optical transmittance when the conventional dense ITO is Therefore, refractive index is used to qualify not only the ˝nal product for supply, but also to monitor batch to batch variation of incoming raw slurry and validate the blend addition steps. In long-term studies at a leading-edge analog device fab, refractive index measurements have replaced auto-titration in qualifying H2O2 concentration in slurry delivery systems.

2020-09-02 · A bandgap of 3.26 eV and a refractive index of 2.36 were obtained, consistent with the previous reports for WO 3 films. The pinhole-free films were found to be a mixture of hexagonal and monoclinic WO 3 , with an increasing monoclinic nature after annealing. Electrodes with tungsten oxide (WO3) having a refractive index of 1.9 showed high transmittance (T = 90.5%) at 460 nm and low sheet resistance (Rs = 11.08 Ω/sq), comparable with those of indium tin oxide (ITO, T = 86.4%, Rs = 12 Ω/sq).

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. 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.
