The thermoluminescence (TL) response of Dy and Li doped 20CaB₄O₇–80CaB₂O₄ (wt % ) glass–ceramic irradiated with ultraviolet (UV) radiation was studied. In order to act as TL activator ions, the Dy and Li ions were included in the matrix during the melting process to increase its TL efficiency. A single crystalline CaB₂O₄ phase was present in the glass–ceramic as determined by X-ray diffraction (XRD). The glass–ceramic 20CaB₄O₇–80CaB₂O₄:Dy,Li wt % (named 20CBO7:Dy,Li) is a newly prepared TL material. Its thermoluminescent dosimetric characteristics have shown a linear response under UV radiation exposure and a good TL signal reproducibility, thus proving to be a promising material for using as an ultraviolet radiation dosimeter.
