The structure, morphology, electrochemical and electrochromic performance of the Nb₂O₅/TiO₂ film are improved via the systematic study of TiO₂ electrodeposition period. X-ray diffraction shows that TiO₂ is amorphous and Nb₂O₅ is orthogonal. The vibration modes and structural properties are studied by the Raman spectroscopy. The chemical compositions, elemental states, and surface features are studied via the X-ray photoelectron spectroscopy. The effects of TiO₂ electrodeposition periods on the morphology of Nb₂O₅/TiO₂ films are analyzed by the field emission scanning electron microscopy. These results show that NTO-20 film has high efficiency Li⁺ reaction kinetics, which shows remarkable electrochromic properties, including wide transmittance modulation (76.94 %), good reversibility (98.15 %), large coloration efficiency (91.6 cm²/C) and high cycle stability.

In automotive display panels, unique electro-optical characteristics are required to control blocking or transmission only from the driver's direction while always being well observed from the passenger's direction. In this study, we developed a viewing angle control technology using double-stacked twisted nematic liquid crystal (TN-LC) films with excellent light-blocking performance only in the driver's direction over wide polar angle ranges in the privacy mode. By configuring the two TN-LC films in ordinary-ray mode and the other in the extraordinary-ray mode, the light could be completely blocked in the privacy mode, whereas it remained well transmitted in the normal mode in a specific left direction. Moreover, using double-stacked TN-LC films, light leakage at high polar angles in the privacy mode can be completely eliminated even without an optical compensation film, which is typically used to eliminate light leakage at high polar angles.

A comparison between TiO₂ and TiO₂-PMMA composite thin films is described with respect to various optical properties and their application in optical coatings for high-energy laser applications. The refractive index and bandgap of TiO₂ are tailored by controlling the TiO₂ sol: PMMA volume ratio. The refractive index varies in the range of 2.4 to 2.0 at 550 nm by controlling the TiO₂: PMMA composition. Incorporation of PMMA leads to reduction in absorption from 1000 ppm to 20 ppm in the composite films, which is attributed to passivation of defect states. In addition, incorporation of PMMA into the TiO₂ sol results in the filling of voids and a significant improvement in surface figure (from λ/6 to λ/10) of the composite films.
