Lanthanum oxycarbonate (La2O2CO3) hollow microspheres with novel porous architectures were successfully fabricated by a simple one-pot hydrothermal treatment of an aqueous solution containing glucose, La(NO3)3·6H2O, and subsequent calcination. The as-prepared La2O2CO3 porous hollow spheres are composed of nanoparticles with a mean particle size of 15 nm. Carbon microspheres act as not only templates but also carbon sources for the formation of La2O2CO3 hollow spheres. Interestingly, the as-prepared La2O2CO3 hollow spheres show a green emission band under UV excitation, which may be used as fluorescent biological labels.
