Study of the optical properties of a NiO/AuNP/NiO nanocomposite film transferred onto a transparent flexible substrate

In this work a technique for optically active nanocomposite structures consisting of an oxide matrix with plasmonic NPs were demonstrated. A nanocomposite film was formed on a silicon substrate by NiO oxide matrix sputtering and gold nanoparticles dewetting. Studies of the morphology, elemental composition, and structure of the nanocomposite using SEM, EDS, XRD methods are presented. The transfer of the film onto a polymer substrate made it possible to study the optical characteristics of the obtained structures. It is shown that formed nanocomposite coatings on a polymer substrate are highly flexible and exhibit excellent mechanical properties.

Amorphous-crystalline Heterostructured Niobium Oxide as Two-in-One Host Matrix for High-Performance Lithium-Sulfur Batteries

Advanced host materials are requisite for both cathode and anode in the development of high-performance lithium-sulfur (Li-S) batteries. Herein, we for the first time report a unique niobium oxide matrix...
