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

Abstract  A sort of surface fine-decorated in situ Tb 2 O 3 nanoparticles in ethanol sols were successively prepared by focused pulsed laser ablation at the interface of Tb 2 O 3 target submerged in flowing liquid containing modifiers, and it is found that the nanoTb 2 O 3 sol decorated by acac and 2,2′-bipy can emit very intense characteristic fluorescence at 549 nm of Tb 3+ ions, which is different from nondecorated nanoTb 2 O 3 ethanol sols with only low fluorescence at 415 nm.
