摘　　要：合成了稀土钐配合物Sm(OPri)β2,并与油墨用改性醇酸树脂等复配,考察不同β-二酮如α-噻吩甲酰三氟丙酮(HTTA)、二苯甲酰甲烷(HDBM)、乙酰丙酮(HAA)对油墨基质的荧光性能的影响。紫外光谱(UV)结果表明,掺杂稀土配合物后,217nm处的紫外吸收峰显著增强。荧光光谱(FS)表明,掺杂配合物Sm(OPri)(DBM)2或Sm(OPri)(AA)2,油墨基质主要呈现位于460nm附近醇酸树脂荧光发射峰;而掺杂Sm(OPri)(TTA)2配合物在365nm波长激发下,在562nm、598nm、644nm处发射较强的Sm3+离子4G5/2→6H5/2,4G5/2→6H7/2,4G5/2→6H9/2跃迁的特征荧光。The complex Sm（OPr^i）132, containing β-diketone （HTTA, HDBM or HAA） was synthesized and the influences of different β-diketone group on luminescence property of modified alkyd resin printing ink base doping with Sm（OPr^i）β2 complex were studied. The results showed that the UV absorption of modified alkyd resin doping with Sm（OPr^i）β2 complex were greatly increased at 217 nm, moreover the modified alkyd resin doping with Sm（OPr^i）（DBM）2 or Sm（OPr^i）（AA）2 complex exhibited luminescence of alkyd resin in 460 nm. Whereas the modified alkyd resin doping with Sm（OPr^i）（TTA）2 exhibited strong characteristic luminescence of samarium ion ^4G5/2→^6H5/2, ^4G5/2→^6H7/2, ^4G5/2→^6H9/2 in 562 nm, 598 nm, 644 nm respectively in 365 nm excitation.
