Abstract
In the present work, polycrystalline samples of MgB4O7 doped with terbium at different concentrations were synthesized using the solvent evaporation method. The sample doped with 1mol% of Tb presented the highest luminescence intensity. The glow curve of the samples showed an intense and well defined TL peak having the maximum on 220°C and a small shoulder peak at ∼330°C. TL spectra and fluorescence of 1mol% doped sample presented a strong Tb3+ emission lines at 489, 545, 588 and 622nm. The TL dose response was measured over the gamma dose range between 1 and 10Gy. The relationship between peak intensity and dose was linear and the minimum detectable dose obtained by interpolation taking into account three times the standard deviation of the zero dose reading was 50μGy.
