Aqueous Conversion of Fructose Phosphate Precursor Nanoparticles into Emissive C‐Dot Composite Nanoparticles

A one-pot, fully water-based synthesis of blue- and red-emitting C-dots is presented. To this concern, [ZrO]2+[F6P]2− [Eu(OH)]2+[F6P]2− precursor nanoparticles (F6P: D-fructose-6-phosphate) are prepared in water converted to C-dot@[ZrO]2+[HPO4]2− C-dot@[Eu(OH)]2+[HPO4]2− composite boiling (100 °C) via microwave heating. Composition, structure, fluorescence the validated by different analytical methods (e. g., FT-IR, EA, TG, DLS, SEM, TEM, EDXS). The resulting aqueous suspensions characterized high colloidal stability intense emission. Specifically, exhibits Eu3+-type red emission water. one-pot with fructose-containing structure phosphate-stabilized C-dot reported for first time.
