Popis: Zinc oxide is evaluated as a fluorescent powder for the detection of fingermarks on non-porous surfaces. Pure and lithium-doped nanostructured zinc oxide powders were characterized using scanning electron microscopy, X-ray diffraction, and fluorescence spectroscopy. The zinc oxide powders were applied to fresh and aged fingermarks deposited on non-porous surfaces such as glass, polyethylene and aluminium foil. Zinc oxide was found to produce clear fluorescent impressions of the latent fingermarks when illuminated with long-wave UV light.
