Towards a fully automated instrument for the advanced characterisation of trapped-charge luminescence signals: The NAUTILUS proof-of-concept
Year: 2025
Type: article
Abstract: A Risø TL/OSL reader and a Horiba Fluorolog-QM spectrofluorometer were coupled using an optical fibre bundle to form a novel instrument, the N ext-generation AU tomated T rapped charge I nduced LU minescence S pectroscopy (NAUTILUS) instrument. The combined capabilities of the two instruments forming the NAUTILUS open up the possibility to perform a large range of luminescence measurements to characterise radiation-induced luminescence signals. The NAUTILUS can carry out sequences of irradiation, preheating, annealing, and advanced luminescence measurements, such as photoluminescence (PL) or radiophotoluminescence (RPL) spectroscopy, PL at elevated temperature, optically stimulated luminescence (OSL) stimulation and emission spectroscopy, and/or bleaching across the visible spectrum. The NAUTILUS also allows for nanosecond time-resolved PL or OSL measurement using pulsed lasers or diode sources. These measurements can be carried sequentially on up to 48 samples without the need to move the samples between instruments, thus improving both measurement reproducibility and throughput. The aim of this contribution is to demonstrate the capabilities of the NAUTILUS using well-known dosimetric materials, such as Al 2 O 3 :C,Mg, Al 2 O 3 :C, MgB 4 O 7 :Ce,Li, and Ag + -doped phosphate glass. By doing so, we demonstrate the NAUTILUS’ capability to perform in-situ irradiation, heating, and reliable advanced luminescence measurements, sequentially on up to 48 samples, with results in agreement with those reported in the literature.
