Unveiling Hidden Prints: Optically stimulated luminescence for latent fingerprint detection [PDF]

open access: yesHeliyon, 2023
Fluorescent lighting and optical techniques have been widely utilized to enhance the detection of latent fingerprints. However, the development of new techniques is imperative to expand the range of surfaces from which latent fingerprints can be detected.

Simulation of optically‐stimulated luminescence of zircon [PDF]

open access: yesphysica status solidi c, 2007
AbstractMineral zircon, ZrSiO4, belongs to a class of materials that can be used as a chronological tool in geology and archaeology for measurements of the natural radiation dose and the sample age by optical methods. The model of optically stimulated luminescence developed earlier is used to investigate the applicability of the single‐aliquot ...

Evaluation of the orientation dependence of optically stimulated luminescence dosimeters in computed tomography dosimetry using an anthropomorphic phantom under clinical imaging conditions [PDF]

open access: yesFujita Medical Journal
Objective: Small dosimeters such as optically stimulated luminescence dosimeters (OSLDs) and thermoluminescence dosimeters (TLDs) are used in anthropomorphic phantoms to measure actual organ exposure in X-ray computed tomography (CT) examinations. Nagase-

Optically stimulated luminescence of alexandrite

open access: yesOptical Materials: X
We report the optically stimulated luminescence (OSL) of natural alexandrite (BeAl2O4:Cr3+) from Brazil. Luminescence was stimulated using 470 nm blue, 525 nm green and 850 nm infrared light.

Waterproofing pellets for Optically Stimulated Luminescence dosimetry

open access: yesBrazilian Journal of Radiation Sciences, 2022
Several doped materials are being studied for dosimetric application, but when some dopant is used with the aim to increase the sensibility, some of these can increases the hygroscopic properties of the sample, which is not suitable for dosimetry. If the
