Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Atomically precise lateral modulation of a two-dimensional electron liquid in anatase TiO2 thin films

, 2017
Engineering the electronic band structure of two-dimensional electron liquids (2DELs) confined at the surface or interface of transition metal oxides is key to unlocking their full potential.

Facet‐Selective Electrostatic Assembling of 2D Mxene onto Anisotropic Single‐Crystal Metal Oxides for Enhanced Photocatalysis

Advanced Materials, EarlyView.
Overcoming random aggregation, Facet‐Selective Electrostatic Assembly (FSEA) achieves site‐specific integration of 2D MXenes onto 3D TiO2 supports. This electrostatic assembling creates optimized interface energy junctions that facilitate spatial charge transfer.

Stability and Electronic Properties of TiO2 Nanostructures With and Without B and N Doping [PDF]

, 2009
We address one of the main challenges to TiO2-photocatalysis, namely band gap narrowing, by combining nanostructural changes with doping. With this aim we compare TiO2's electronic properties for small 0D clusters, 1D nanorods and nanotubes, 2D layers ...

Room Temperature Synthesis and Photopatterning of Mesoporous Titanium Dioxide Thin Films

Advanced Materials Technologies, EarlyView.
A nanofabrication strategy combining deep‐UV photolithography with block copolymer self‐assembly enables direct patterning and mineralization of mesoporous TiO2 thin films at room temperature. Photocatalytic titanium oxo‐clusters promote polymer degradation under UV irradiation, enabling multiscale control over porosity, film thickness, and lateral ...

Polarization‐Sensitive Au‐TiO2 Nanopillars for Tailored Plasmonic Enhanced Light‐Driven Reaction Activity

Advanced Optical Materials, EarlyView.
Manipulating the product generation yield is achieved on a model plasmonic resonance‐driven reaction by tuning the nonthermal effects of localized surface plasmonic resonance on an elliptical Au‐TiO2 nanopillar metasurface. Asymmetric configuration of the elliptical nanopillar array governs the polarization‐dependent optical properties redshifting the ...

Tunable Polaronic Conduction in Anatase TiO2 [PDF]

, 2018
Oxygen vacancies created in anatase TiO2 by UV photons (80–130 eV) provide an effective electron-doping mechanism and induce a hitherto unobserved dispersive metallic state. Angle resolved photoemission reveals that the quasiparticles are large polarons.
