摘　　要：以稀土铽、对甲基苯甲酸、邻菲罗啉为原料合成铽三元荧光配合物,以水为溶剂,加入表面活性剂和铽配合物制成小颗粒悬浮液,用于常见非渗透性客体表面潜在手印的显现,并对悬浮液显现手印条件进行优化。结果显示合成的铽荧光配合物在365 nm紫外灯照射下发出绿色荧光;配置悬浮液显出手印纹线清晰,细节特征明显;材料具有优异荧光特性和广泛适用性。Terbium ternary fluorescent complexes were synthesized with rare earth terbium,p-toluic acid and o-phenanthroline as raw materials,using water as solvent,adding surfactants and terbium complexes to prepare a small particle suspension,which was used to develop the latent f ingerprints on various of smooth substrates,and the develop conditions were optimized.The results showed that the synthesized terbium fluorescent complexes emit green fluorescence under the irradiation of 365 nm UV.The conf iguration suspension developed latent f inger prints with clear handprint lines and obvious details.The material had excellent fluorescent properties and wide applicability.
