Hydrothermal Synthesis Nano FAP : Nd3+ as Biological Probe with Near-Infrared to Near-Infrared Luminescence

摘要

Biocompatible nano Nd3+ doped Ca5(PO4)3F( FAP) were successfully synthesized through hydrothermal method. Nearly pure near-infrared to near-infrared (NIR-to-NIR) luminescence can be realized. Moreover, the excitation and the emission at 808 and 1060 nm are away from the visible region. These are beneficial to deeper tissue penetration and reduced autofluorescence. This material exhibits an excellent NIR-to-NIR emission performance and is thus potentially applicable as an high-contrast in vitro and in vivo imaging.
