Abstract :
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.
