Abstract

Organic-inorganic hybrid fluorescent microspheres (OI-FMs) without typical fluorophores were prepared. Fluorescence quantum yield of OI-FMs is up to 70.0% after being heated in an oven at 120 °C (named as OI-FMs-120). Interestingly, OI-FMs-120 shows different detection performances in different solvents. It can be used for qualitative and quantitative detection of Fe with a detection limit of 37.8 nM in absolute ethanol. While in aqueous solution, it can be applied as an ON-OFF-ON fluorescent probe. Fluorescence of the probe is quenched by Hg and later recovered by biothiols. The detection limit is as low as 34.9 nM for Hg, 91.0 nM for Cys, 0.12 μM for Hcy and 0.13 μM for GSH in aqueous medium, respectively.
