Abstract

This article focuses on the synthesis and forensic application of mixed metal oxides (BZAC, comprising barium, zinc, aluminum, and cerium oxides) nanophosphors for latent fingerprint (LFP) detection. The nanophosphors were produced via gamma irradiation of precursor solutions followed by a solution combustion method, resulting in crystalline particles averaging 30 nm in size with a bandgap of 3.18 eV and blue luminescence emission bands at 432, 444, and 460 nm. When applied as a powder dusting agent, the BZAC nanophosphors enhanced the visibility of latent fingerprints under 370 nm UV light on various surfaces, providing clear and distinct ridge patterns. These findings suggest that BZAC nanophosphors are promising luminous materials for improving fingerprint imaging in forensic investigations.
