中文摘要	uniform, ultra-small-sized and well-water-dispersible laf3 nanoparticles doped with trivalent rare earth (re) ions (eu3+ or tb3+) have been synthesized by a simple, low temperature synthesis route. the nanoparticles, with sizes of about 3.2 nm (for those doped with eu3+) and 3.0 nm (for those doped with tb3+), are roughly spherical and monodisperse. 1,2,4,5-benzenetetracarboxylic acid (labeled as ba) as sensitizer has been bonded to the surface of the nanoparticles, which can sensitize the emission of re3+ in the laf3 nanoparticles. the ba-laf3:re3+ (re = eu or tb) nanoparticles have a broad absorption band in the uv domain, and show enhanced luminescence of re3+ based on an energy transfer from ba ligands to re3+ ions (i.e. the so-called "antenna effect''). due to the dual protection of organic ligands (ba) and inorganic matrices (laf3), ba-laf3:re3+ (re = eu or tb) nanoparticles have longer excited state lifetimes than laf3:re3+ (re = eu or tb) nanoparticles as well as lanthanide coordination polymers of ba.
