  Formation Mechanism of Carbogenic Nanoparticles with Dual Photoluminescence Emission

  摘要：

  We present a systematic investigation of the formation mechanism of carbogenic nanoparticles (GNPs), otherwise referred to as C-dots, by following the pyrolysis of citric acid (CA)-ethanolamine (EA) precursor at different temperatures. Pyrolysis at 180 degrees C leads to a CNP molecular precursor with a strongly intense photoluminescence (PL) spectrum and high quantum yield formed by dehydration of CA EA. At higher temperatures (230 degrees C) a carbogenic core starts forming and the PL is due to the presence of both molecular fluorophores and the carbogenic core. CNPs that exhibit mostly or exclusively PL arising from carbogenic cores are obtained at even higher temperatures (300 and 400 degrees C, respectively). Since the molecular fluorophores predominate at low pyrolysis temperatures while the carbogenic core starts forming at higher temperatures, the PL behavior of CNPs strongly depends on the conditions used for their synthesis.

  The present invention relates to a powder composition, in particular a fingerprint powder composition for the visualisation of latent fingerprints. Such fingerprint powder compositions comprise carbogenic nanoparticles which, when mixed with a suitable diluent (including any existing or future fingerprint powders), exhibits excitation-dependent emission properties which enable the fingerprint powder compositions and imagable fingerprint impression patterns formed thereform to be imaged in a variety of different colours by simply varying the wavelength(s) of any excitation radiation. As certain backgrounds can render visualisation of fingerprint impression patterns very difficult, having the flexibility to judiciously tune the foreground colour of the fingerprint impression patterns is a significant advantage since it permits instantaneous improvements in visualisation without needing to resort to using a different fingerprint powder. The invention also relates inter alia to corresponding methods and specialised apparatus for fingerprinting.

  本发明涉及一种粉末组合物，特别是用于潜伏指纹可视化的指纹粉末组合物。这种指纹粉末组合物由碳源纳米粒子组成，当与适当的稀释剂（包括任何现有或未来的指纹粉末）混合时，这种纳米粒子具有随激发而发射的特性，只需改变任何激发辐射的波长，就能将指纹粉末组合物及其形成的可视指纹印迹图案成像为各种不同的颜色。由于某些背景会使指纹印迹图案的可视化变得非常困难，因此灵活地调整指纹印迹图案的前景颜色是一项重大优势，因为这样可以立即改善可视化效果，而无需使用不同的指纹粉末。除其他外，本发明还涉及指纹识别的相应方法和专用设备。
