“…In a quest to achieve high resolution of latent fingerprints on porous and non-porous surfaces, research groups studied the applicability of luminescent lanthanide NP powders. The NP optical proprieties, small size, versatility and ability to specifically tune their surface properties are the main reasons why they attract so much attention in the fingerprint application [17][18][19][20][21][22][23][24][25]. However, the interaction between NP and fingerprint residues are considered as a physical adherence that should lead to a lower sensitivity and higher detecting limit.…”

A series of green emitting Gd 2 O 3 :Tb 3+ (Tb: 0%-10% mol) nanoparticles (NP) were synthesized using the hydrothermal method, then characterized and evaluated for latent fingerprint visualization. X-ray diffraction study (XRD) revealed a cubic structure of the nanoparticles and the total incorporation of the terbium in the Gd 2 O 3 matrix. Field Emission-Scanning Electron Microscopy (FESEM), Energy Dispersive x-ray Spectrometry (EDX) and Transmission Electron Microscopy (TEM) were used to study the morphology and the elementary composition of the NP. Photoluminescence (PL) studies showed strong green emission around 540 nm due to the transition 5 D 4 → 7 F 5 . The luminescence color of the synthesized NP was characterized by the CIE 1931 chromaticity diagram. The potential use of the NP powders for the visualization of latent fingerprint under UV irradiation was assessed on various substrates. The latent fingerprint images revealed by the Gd 2 O 3 :Tb 3+ NP powders are clear enough to extract and analyze reliable fingerprint features. The fingerprint quality was evaluated using three fingerprint quality assessment metrics and by extracting and measuring the visibility of the minutiae. The experimental results show very good quality images of the latent fingerprint acquired using the Gd 2 O 3 :Tb 3+ NP and yield good minutiae extraction.
