KRI has been successful in conducting many sol–gel related projects. In this article, we review KRI’s sol–gel projects that fall into the following four categories: zero dimensions (particle applications), one dimension (fiber applications), tw

VχTi1−χO2 films with various V contents (χ=0–0.1) were prepared on pyrex glass substrates by a sol–gel method. X-ray diffraction (XRD) measurements revealed that all the films crystallized in anatase after heat-treatment at 500 °C for 1 h,

We observed UV-stimulated hydroxylation at the surface of ZnO crystals. Reactive defective sites were initially formed in the surface layer via photoreduction induced with energetic photons above the band gap of ZnO. Hydroxyl groups were produced by

TiO 2 /poly(dimethylsiloxane) (PDMS) hybrid films with various ratios were prepared on poly(methyl methacrylate) (PMMA) substrates by a sol–gel method. The films were highly transparent (transmittance>90%), and amorphous TiO 2 in the films crystall

Structural changes in sol-gel films with photo-irradiation were investigated using zinc oxide (ZnO) derived from zinc acetate. The exposure of the films to an ultraviolet lamp induced hexagonal ZnO crystals in a relatively dense amorphous structure.

The resistivity of sol-gel-derived indium tin oxide (ITO) films effectively decreased with crystallization by exposure to a low fluence UV beam (10–20 mJ/cm2) from an ArF laser. The increase in temperature at the surface of the films was below 10°

Structural changes stimulated by UV light irradiation for sol-gel-derived amorphous ZnO were investigated. Transformation of amorphous ZnO into the wurtzite phase was achieved by irradiation of 4.9 eV photons in air using a conventional low-pressure

Ultraviolet illumination with photon energy above 4.9 eV resulted in photodarkening on sol–gel-derived amorphous ZnO films. Photoreduction of ZnO to Zn metal was achieved by irradiation with energetic photons above 6.7 eV. These changes basically o
