Refinement of the structure of anatase at several temperatures [PDF]

Zeitschrift für Kristallographie - Crystalline Materials, 1972
The crystal structure of anatase was refined at several temperatures between 25°C and 800°C using single-crystal x-ray diffraction data. The only structural parameter, the z coordinate of oxygen, changes regularly from 0.2081(2) at 25°C to 0.2076(3) at 800°C.

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
