WebSep 30, 2024 · Aggregation-induced emission (AIE) fluorophores with second near-infrared window (NIR-II) fluorescence are very promising for in vivo imaging because they emit fluorescence in an aggregated state and provide desirable imaging resolution and depth. Up to now, only a limited number of NIR-II AIE fluorophores have been developed. WebMay 25, 2024 · For the photocatalytic dye decolorization, pH is one of the considerable parameters as it can affect the dye reaction rates in numerous ways. Since catalyst surface charge is dependent on pH of a given solution, pH can affect adsorption of dye on the surface of semiconductor [76].
