摘要
A new europium (Ⅲ) complex Eu(HFNH) 3Phen (HFNH: 4, 4, 5, 5, 6, 6, 6-heptafluoro-1-(2-naphthyl)hexane-1,3-dione; phen: 1,10-phenanthroline) was synthesized and its triboluminescent phenomenon was observed. Photoluminescence and triboluminescence spectra were successfully determined. The most intense triboluminescent emission originates from the transition of the central Eu 3+ ion from 5D 0 level to 7F 2 level. The triboluminescent spectrum is basically similar to that of photoluminescence, which correlates with the disorders of F atoms.
