Latent Fingermarks Development with Mercaptosuccinic Acid Modified CdTe Quantum Dots on Various Substrates
Abstract:
Prominent fingermarks were obtained within 1~3 seconds after developed by the water-soluble mercaptosuccinic acid(MSA) modified CdTe quantum dots(QDs) with a wide-continuous excitation spectra and a narrow-symmetric emission spectra on various substrates.Latent fingermarks on water-immersed substrate and sticky adhesive tape were developed successfully.High sensitivity was also obtained on the development of latent fingermarks pressed continuously with the same finger.Compared with methyl violet,rhodamine 6G and mercaptoacetic acid(TGA) modified CdTe QDs,the MSA modified CdTe QDs showed the fastest developing speed and the best fingermarks quality.
