BaY2F8:Yb3+/Er3+ nanobelts were prepared with oleic acid as capping ligand. Under 980 nm excitation, the H-2(9/2)-> I-4(15/2), F-4(7/2)-> I-4(15/2), H-2(11/2)-> I-4(15/2), S-4(3/2)-> I-4(15/2), and F-4(9/2)-> I-4(15/2) transitions were observed. The intensity ratio of H-2(11/2)/S-4(3/2)-> I-4(15/2) to F-4(9/2)-> I-4(15/2) and H-2(11/2)-> I-4(15/2) to S-4(3/2)-> I-4(15/2) increased with increasing excitation power.
