“…A main peak at approximately 469 nm and several peaks in the range of 400-600 nm were observed in the PL spectrum of WO3-600 °C, which is in agreement with the results from Ref. [32]. In the case of WO3-800 °C and WO3-12 h with an m-WO3/ h-WO3 junction, the shape of the curves is similar to that of WO3-600 °C, whereas the peak intensities significantly decrease.…”

“…However, some metal oxide NPs show promising optical and electrochemical properties for ECL. In this group, ZnO, [42] TiO 2 , [43] SnO 2, [44] and WO 3 , [45] NPs have been studied for ECL and their ECL characteristics are summarized in Table 2.

Compared to fluorescence, electrogenerated chemiluminescence (ECL) can be a superior analytical tool in terms of sensitivity and signal-to-noise ratios, owing to the absence of background emissions from unwanted photoexcitation. Semiconductor nanoparticles (NPs) are highly promising in many analytical applications, because they can produce stable ECL and possess surface-dependent, tunable ECL properties. This Minireview gives a brief overview of ECL energetics and processes, the current progress of ECL of semiconductor NPs, and recent advances in biological sensing based on ECL of semiconductor NPs. The current challenges and perspectives on ECL of semiconductor NPs and their biological sensing applications are also discussed.

Although the nitrous oxide belongs among three of the most contributing greenhouse gases to global warming, it is quite neglected by photocatalytic society. The g-CN and WO composites were therefore tested for the photocatalytic decomposition of NO for the first time. The pure photocatalysts were prepared by simple calcination of precursors, and the composites were prepared by mixing of suspension of pure components in water followed by calcination. The structural (X-ray diffraction, X-ray photoelectron spectroscopy, high-resolution transmission electron microscopy), textural (N physisorption), and optical properties (diffuse reflectance spectroscopy, photoluminescence spectroscopy, photoelectrochemical measurements) of all composites were correlated with photocatalytic activity. The experimental results and results from characterization techniques confirmed creation of Z-scheme in the WO/g-CN composites, which was confirmed by hydroxyl radicals' trapping measurements. The photocatalytic decomposition of NO was carried out in the presence of UVA light (peak intensity at 365 nm) and the 1:2 WO/g-CN composite was the most active one, but the photocatalytic activity was just negligibly higher than that of pure WO. This is caused by relatively weak interaction between WO and g-CN which was revealed from XPS.
