Low-temperature growth of SiCN nanoparticle films on an AlN buffer layer on Si (100) by consecutive RF magnetron sputtering is reported. The visible photoluminescence (PL) is observed between 620 and 670 nm using a single photo excitation at 514.5 nm. The growth of film at room temperature is found to yield the strongest PL intensity, whereas the film grown at 200°C corresponds to the lowest PL intensity. A similar variation of SiC diffraction intensity is also observed in XRD spectra. The photoluminescence of the SiCN film is discussed on the base of the morphological, structural and elemental analyse.

Abstract Catalysts made of in-situ exsolved metal nanoparticles often demonstrate promising activity and high stability in many applications. However, the design of these catalysts is greatly constrained by the classic exsolution mechanism, which occurs almost exclusively through substitutional metal-doping in perovskites. Here we show that metal nanoparticles can also be in-situ exsolved from interstitially doped metal cations in a NiOOH supporting framework with the guidance of theoretical calculation. The exsolution can be conducted swiftly at room temperature. A novel copper nanocatalyst prepared with this approach have a quasi-uniform size of 4 nm delivering an exceptional CO faradaic efficiency of 95.6% with a notable durability for the electrochemical reduction of CO2. This design principle is further proven to be generally applicable to other metals and foregrounded for guiding the development of advanced catalytic materials.

Nanoparticle Film

A zinc oxide (ZnO) nanoparticle gas sensor was formed by spin coating. We annealed the film at 400, 600, and 800°C for 1 h in air to create a gas sensor. The responses of the gas sensor to ethanol under UV light illumination were investigated. We found that the ZnO nanoparticle film annealed at 800°C had the highest sensitivity. This can be attributed to the fact that the defects of ZnO nanoparticle film annealed at 800°C are considerably more than those for the film annealed at other temperatures. This study demonstrates that ZnO nanoparticles have potential applications as room-temperature ethanol sensors.
