摘要合成了四种新的铕配合物，并研究了它们的机械发光性质。在四种化合物中，只有三(2-噻吩甲酰基三氟丙酮)邻菲咯啉(Eu(TTA)3(Phen))表现出强烈的机械发光。测量了它的光谱，发现它的光谱与光致发光的光谱基本相同，表明它的发射物种相同。文中还讨论了机械发光的激发机制。
Abstract Four new kinds of europium complexes were synthesized and their mechanoluminescent properties were investigated. Out of the four, only europium tris(2-thenoyltrifluoroacetone) phenanthroline (Eu(TTA)3(phen)) exhibited intense mechanoluminescence. Its spectra were measured and found to be essentially the same as that of the photoluminescence, indicating an identical emitting species. The excitation mechanisms of mechanoluminescence are also discussed.
