Hybrid Rare Earth Complexes as Luminescent Probes in Bioimaging

5 Hybrid Rare Earth Complexes as Luminescent Probes in Bioimaging 

In addition. Yuan and coworkers described spherical silica-based luminescent europium nanoparticles with a uniform size of about 10 nm in diameter [87]. Interestingly, the nanoparticles can be excited over a wavelength range from the UV to visible light (200 50 nm) in aqueous solution, and could be used for time-resolved luminescence imaging of an environmental pathogen, Giardia lamblia.
