In Situ Interactions of Eu(TTA)3(H2O)2 with Latent Fingermark Components-A Time-Gated Visualization of Latent Fingermarks on Paper

Harnessing long-lived visible phosphorescence to eliminate background interference from fingermark images

Minimising background fluorescence can enhance the visible details of treated fingerprints. Here, a 4-tpt fingerprint powder exhibiting long-lived phosphorescence is applied to this end. The powder was found to suppress background fluorescence, including on challenging surfaces, when using standard forensic equipment and eschewing specialized or bespoke imaging techniques.
