Abstract: [Display omitted] • LaFeO 3 has been synthesized through sol–gel method. • Glycine was used as fuel for synthesis. • Absorption and emission studies were discussed. • XRD, SEM, and XPS characterizations of LaFeO 3 discussed. • Levels (I II, and III) of LFPs were visualized and identified. Latent fingerprints are considered a primary source of best reference for personal identification in criminal investigations. However, poor resolution, less background hindrance, and sensitivity over fingerprint ridges are often problems in fingerprint development. To address these issues, special care is required by developing new fluorescence materials. As a result, this effort was made to synthesize lanthanum ferrite (LaFeO 3) fluorescent nano perovskite oxide by the sol–gel method using glycine as fuel, to detect three (I, II, and III) levels of fingerprints. In addition, the absorption spectrum was recorded in a dispersed medium, and dual peaks at 329 and 406 nm in visible regions were obtained, followed by the photoluminescence spectra that showed a broad peak at 527 nm with chromaticity coordinates. Powder X-ray diffraction confirms the synthesized LaFeO 3 orthorhombic phase with a crystallite size of 54 nm, and the morphology of LaFeO 3 was found to be highly monodisperse. X-ray photoelectron spectroscopy confirmed that La has + 3 with Fe + 3 oxidation states, and Infrared spectroscopic techniques revealed all functional groups were present uniformly. The powder dusting method was applied on various porous and non-porous surfaces, revealing distinct ridges of fingerprints without background hindrance and with precise sensitivity; this proves LaFeO 3 is suitable for forensic science.
