Abstract
The fluorescent quinolinyl hydrazone (QH) development for latent fingerprint and anticounterfeiting detection under UV illumination has not yet been adequately researched. In this sense, this work presents the fabrication and characterization of QH for latent fingerprint and security ink applications. The fluorescence properties of QH were studied in different surrounding mediums (Powder, PVB, silica, and DMF). QH exhibited intensive greenish-blue luminescence with spectacular visual emission under unharmful UVA excitation. Based on the highly luminescent character of QH, latent print details, including their characteristic three levels, have been identified from various forensic substrates (non-porous, semi-porous, and porous). QH has, moreover, been used to develop luminescent ink for anti-counterfeiting applications.
