Highly Stable Colloidal Lithium Niobate Nanocrystals with Strong Violet and Blue Emission.

High-quality LiNbO colloidal nanocrystals were synthesized by the sol-gel technique. Morphological, structural, and optical spectroscopy methods were used to characterize LiNbO colloidal nanocrystals. To investigate the optical properties, UV-visible absorption spectroscopy was used, which showed that the absorption peak was around 250 nm.

Self-templated synthesis of uniform nanoporous CuCoO double-shelled hollow microspheres for high-performance asymmetric supercapacitors.

Multilevel interior nanoporous CuCoO microspheres have been for the first time developed using a facile self-templated method. Electrochemical results in three- and two-electrode systems show that the double-shelled hollow microsphere electrode is a promising candidate for high-performance supercapacitors.
