AbstractClassical pH test papers are widely used to measure the acid base degree of media in a qualitative or semiquantitative manner. However; extension of portable and inexpensive methods to a wide range of analytes so as to eliminate the tediousness of instrumental assays remains unsuccessful. Here, we report a novel kind, of dual-colored carbon dot (CD) ratiometric fluorescent test paper for the semiquantitative assay of copper ions (Cu2+ by a dose sensitive color evolution. The preparation of the test paper is based on the following two interesting findings: on the one hand, residual p-phenylenediamine at the, surface of as synthesized red CDs (r-Cbs) efficiently binds CO2+ ions to produce a strong visible absorption that overlaps, the emission of blue CDs (b-CDs); on the other hand, the ions render the adsorption of small b-CDs onto the surface of larger r-CDs, through their dual-coordinating irteractions with: the surface ligands of both r-Cbs and b-CDs. These two mechanisms lead to a specific spectral energy transfer to quench the fluorescence of b-CDs with a sensitive detection limit of 8.82 nM Cu2+, whereas the red fluorescence of t-Cbs is unaffected as a stable internal standard. Ratiometric fluorescent test papers have been prepared using a mixture of r-CDs and b-CDs (1:7) ink by jetprinting on a piece of paper. With the addition of Cu2+ ions, the blue test paper produces a consecutive wide-colered evolution from blue to orange-red, with a dose-discerning ability as low as 25 nM.
