چکیده انگلیسی
Optical, radioluminescence (RL) and thermoluminescence (TL) properties of magnesium aluminoborate glasses were evaluated. The samples were synthesized by the conventional melt-quenching technique using an alumina crucible under ambient atmosphere. After polishing, all the samples show good transparency. In photoluminescence, RL and TL, the emission is predominantly due to the 5d-4f transitions of Ce3+ appearing as a broad feature peaking around 300-500 nm, and the decay time constants are affected by concentration quenching but on the typical range for the 5d-4f transitions of Ce3+. TL glow curves are characterized as a single but broad glow peak over 100-300 °C, and the TL intensity monotonically increases with the X-ray dose irradiated over 1-10000 mGy.
