In this study, we have designed a one-pot microwave strategy for facile and rapid synthesis of blue-emitting 19F-SiNPs. The as prepared 19F-SiNPs significantly exhibited ultral small sizes, excellent water solubility and strong fluorescence. Besides, The chemically and magnetically equivalent trifluoromethyl groups grafted on the prepared nanoparticles displayed a single NMR signal, which offered advantages to maximize the generated magnetic resonance signal. In summary, such resultant 19F-SiNPs are particularly suitable for real-time 19F-MRI and fluorescence dual modality imaging.
