Dual‐Emission Fluorescent Carbon Dots Grafted by Rhodamine‐B for Selective Detection of Iron Ion and Bioimaging in Cell

Xiaoyan Hu,

et al.

Abstract: Rhodamine‐B grafted carbon dots (RhB‐CDs) with double emission fluorescence are developed , one of which has excitation dependence, while the other have not. The prepared RhB‐CDs have good dispersibility, uniform spherical shape, and excellent water solubility. They could be used to specifically detect Fe3+ ions in an aqueous solution with the detection limit of 1.1 × 10−6 m and with good anti‐interference ability, because Fe3+ ions are easier to combine with hydroxyl groups on the surface of RhB‐CDs to form a… Show more
