| 摘 要： | 目的比较巯基乙酸包覆的硒化镉（CdSe/TGA）和硫化镉/聚酰胺-胺（CdS/PAMAM）量子点溶液显现胶带粘面手印的性能。方法两种材料在显现指纹的过程中,通过比较观察显现时间、显现温度、遗留时间等因素来考察显现效果。结果 CdSe/TGA溶液的荧光强度、显现时间以及材料的稳定性较好;CdS/PAMAM溶液显现的手印纹线流畅,显现细节特征能力强,对陈旧的或微弱的油潜手印的显现效果好。结论两种材料各有所长,对胶带粘面手印有良好的显现效果。

| Abstract: | Objective To explore the capability of CdSe/TGA and CdS/PAMAM quantum dots solutions in developing fingerprints on adhesive tape. Methods The preliminary evaluation was made by analyzing the development time,temperature and effects of both materials. Results The stability and fluorescence density of CdSe/TGA solutions were better than CdS/PAMAM,while CdS/PAMAM was more effective for developing aged fingerprints. Conclusions Each of them has its advantage to develop fingerprints,and this work provides scientific basis for further comprehensive evaluation. |
