It is common sense that emission maxima of phosphorescence spectra (λP) are longer than those of fluorescence spectra (λF). We report a serendipitous finding of up-converted room-temperature phosphorescence with λP < λF and phosphorescence lifetime > 0.1 s in dopant-matrix systems.
We report the use of affordable and widely-available UV-Vis spectroscopy to monitor redox activities during charge storage. The data allowed us to distinguish charge storage mechanisms and quantify the oxidation state changes, similar to synchrotron-based X-ray absorption spectroscopy.
Metal oxide single-component light-powered micromotors for photocatalytic degradation of nitroaromatic pollutants
The extensive employment of nitroaromatic pollutants has led to severe contamination of the environmental waters. Here, we proposed low-cost single-component WO3 microrobots capable of efficient photodegradation of nitroaromatic pollutants in a sustainable way.
