Band-Gap Narrowing of Titanium Dioxide by Nitrogen Doping TiO2-based powder, including 0.1 at% of N doped in the rutile lattice, has been synthesized by oxidation of TiN. As a result, a significant shift of the ab... T Morikawa,R Asahi,T Ohwaki,... - 《Japanese Journal of Applied Phy...
Titanium dioxide (TiO2) is a stable, non-toxic inorganic material. Because of very high refractive index, TiO2 has been widely used as a white pigment. The optimal particle sizes of TiO2 for pigment applications are around 250 nm. The pigmentary applicat
High-quality photonic crystals with a nearly complete band gap obtained by direct inversion of woodpile templates with titanium dioxidePhysics - OpticsPhotonic crystal materials are based on a periodic modulation of the dielectric constant on length scales comparable to the wavelength of light. These ...
Zinc oxide (ZnO) [8] and titanium dioxide (TiO2) [9], [10], [11] were the most popular semiconductor materials investigated in the DSSCs application. This was due to their nontoxicity, wide band gap energy (needed for light absorption), and good carrier mobility. ZnO presents better ...
band gap, the effective HubbardUof 7.2 eV is applied for the Ti 3dstates49(see the influence ofUvalues on the spatial spin polarization results in Supplementary Fig.32). Based on the GGA + Umethod, the calculated band gap of anatase TiO2is 3.3 eV, which is very close to ...

Titanium dioxide hollow spheres (TiO2-HSs) were fabricated by applying carbon spheres (CSs) as templates, which were eliminated by calcination. The most suitable TiO2 was selected and an attempt was made to further increase its photocatalytic activity via noble metal (Au and Pt, at 0.25 wt%) ...
TiO2has a UV-limited photoresponse due to its wide band gap. The electronic properties of TiO2can be easily tuned by linking a PS to its surface. The PS can be either adsorbed or grafted covalently to the surface of TiO2NPs. The formed TiO2–PS system induces an extension of the absorptio...
