摘要
以稀土钐、钇为中心离子、TTA为第一配体,邻菲罗啉为第二配体,使用共沉淀法在50℃、pH值为7的条件下合成了三元稀土荧光配合物Sm_(0.5)Y_(0.5)TTA_(3)(o-Phen)。在365 nm紫外光照射下,合成粉末发出强烈的红色荧光。将Sm_(0.5)Y_(0.5)TTA_(3)(o-Phen)粉末用于客体表面潜在手印显现,考察对比度、灵敏度、选择性和适用性,结果显现的手印纹线流畅,细节清晰,粉末不黏附小犁沟,对比度高,适用性强。此外,该粉末对陈旧潜在手印也具有较好显现效果。
The ternary rare earth fluorescent complex Sm_(0.5)Y_(0.5)TTA_(3)(o-Phen)was synthesized at 50℃and pH 7.The synthetic powder emits intense red fluorescence under 365 nm UV light.Sm_(0.5)Y_(0.5)TTA_(3)(o-Phen)powder was used for the potential handprint on the object surface for the contrast,sensitivity,selectivity and applicability.The resulting fingerprints were smooth with clear details,and the powder did not adhere to small furrows,with high contrast and strong applicability.In addition,the powder also has a good effect on the old potential handprint.
