Study on the surface decorating of nanoTb2O3 in the ethanol sol and its fluorescence characteristics

 A sort of surface fine-decorated in situ Tb2O3 nanoparticles in ethanol sols were successively prepared by focused pulsed laser ablation at the interface of Tb2O3 target submerged in flowing liquid containing modifiers, and it is found that the nanoTb2O3 sol decorated by acac and 2,2′-bipy can emit very intense characteristic fluorescence at 549 nm of Tb3+ ions, which is different from nondecorated nanoTb2O3 ethanol sols with only low fluorescence at 415 nm.
