The interaction of hydrogen with defects in ZnO nanoparticles under H2–Ar mixed gas was investigated by positron annihilation, Raman and photoluminescence spectroscopy. Two series experiments were performed, including annealing the samples pure Ar gas. thermal stability hydrogen-related also carried out subsequent isochronal air. annihilation results showed that more vacancy clusters formed hydrogenated due to reducing effect when compared those annealed gas, which consistent smaller grain...
The effect of hydrogen doping on the magnetic properties ZnO nanoparticles was investigated. Hydrogen incorporated by annealing under 5% H2 in Ar ambient at 700 °C. Room-temperature ferromagnetism induced hydrogenated nanoparticles, and observed could be switched between “on” “off” states through oxygen process, respectively. It found that Zn vacancy OH bonding complex (VZn + OH) crucial to using X-ray photoelectron spectroscopy positron annihilation analysis. Based first-principles...
An investigation of the origin extremely low thermal conductivity and outstanding thermoelectric performance BiSbX<sub>3</sub> (X = S, Se).
In this paper, the photocatalytic process of TiO2 (P25) is directly characterized by using a positron annihilation lifetime spectroscopy (PALS), high-resolution transmission electron microscopy (HRTEM), Photoluminescence (PL) and UV Raman (Raman). The experimental results reveal that: 1) From PALS measurements, because τ1 τ2 values their intensity (I1 I2) assigned to different size amounts defects, respectively, variations indicate formation types defects during absorption degradation. 2)...
