| 英文摘要 | An activated carboxyl-based approach for latent fingerprint development with high quality and high efficiency was proposed. Firstly , carboxyl-functionalized fluorescent europium nanocomplex was chemically synthesized via a one-step process by using europium (III) ion as the luminescence center, phthalic acid as the first ligand , and phenanthroline as the second ligand. Then , the micromorphology , crystal structure , ultraviolet absorption property, fluorescent emission performance, surface functional groups and thermal property of these synthesized europium nanocomplex were characterized by transmission electron microscopy , powder X-ray diffractometer, , ultraviolet-visible spectrophotometer, fluorescence spectrophotometer, Fourier transform infrared spectrometer and simultaneous thermal analyzer, respectively. The carboxyl groups on the surface of europium nanocomplex were further activated using 1- (3 -dimethylaminopropyl) -3 -ethylcarbodiimide hydrochloride combined with N-hydroxysuccinimide. The activated carboxyl groups on the surface of europium nanocomplex could easily react with the amino groups in latent fingerprint through amide reaction , and the latent fingerprint was thus fluorescently developed with high efficiency. The mechanism of latent fingerprint development based on activated carboxyl process was discussed in detail, and the nanocomplex dosage and the staining time in developing suspension were also systematically optimized. In addition , the effects in fingerprint development were investigated from three aspects including contrast, sensitivity and selectivity. Experimental results showed that, the activated carboxyl-based approach could achieve a high performance in latent fingerprint development, exhibiting high efficiency, good operability and wide applicability. |
