Thermoluminescence Spectra of Rare-Earth Doped Calcium Fluoride
This study investigates the thermoluminescence (TL) emission spectra of various doped CaF2 materials after exposure to ionizing radiation. The understanding of the TL spectra of these single-doped materials, systematically produced under the same sintering conditions, contributes to the interpretation of complex TL spectra observed in naturally occurring fluorite crystals. The production of Ce3+, Tm3+, Tb3+, Dy3+, Er3+, Pr3+, Nd3+, and Yb3+ doped calcium fluoride was carried out using the combustion synthesis method. The emission spectrum lines could be ascribed to the RE transitions that occur when a trapped hole center recombines with a RE2+. Emissions range from the ultra-violet to the near-infrared. This study aids in tailoring new materials for specific applications and the matching of emitted light to specific filters and instrumentation used for detection.
期刊介绍:
The Brazilian Journal of Physics is a peer-reviewed international journal published by the Brazilian Physical Society (SBF). The journal publishes new and original research results from all areas of physics, obtained in Brazil and from anywhere else in the world. Contents include theoretical, practical and experimental papers as well as high-quality review papers. Submissions should follow the generally accepted structure for journal articles with basic elements: title, abstract, introduction, results, conclusions, and references.
