Abstract
A novel technique has been developed for the induction of luminescence in latent fingerprints. A gaseous electrical discharge (20 000 V) followed by treatment with the vapours formed by heating ammonium hydrogen carbonate induces UV excited luminescence in latent prints. Good results have been achieved on a number of surfaces and the technique is effective on fresh prints as well as prints up to several weeks of age. Developed prints have remained luminescent over a year after initial treatment and the method does not prohibit the subsequent application of conventional fingerprint development techniques. It can also be used to induce luminescence in prints developed with cyanoacrylate.
