TL -OSL properties of nanosized BaMg2Al6Si9O30:Ce3+/Dy3+ phosphor

In this article we have reported Ce3+/Dy3+ activated BaMg2Al6Si9O30 nanosized phosphor synthesized by the combustion method. Prepared phosphors was initially irradiated by Sr-Y90 beta-emitting source and then it was used for the Thermoluminescence- Optically Stimulated Luminescence (TL-OSL) measurement. Here, BaMg2Al6Si9O30:Ce3+/Dy3+ phosphor exhibits an isolated broad TL glow curve at around 201(0) C. And further, it was well resolved into two sub-bands to estimate the trap depth and TL parameters of the individual glow curve. Along with this, we have carried out the OSL measurement of BaMg2Al6Si9O30:0.1Ce(3+),yDy(3+) phosphor which is well fitted into third order exponential. The micro and nanostructure of the phosphors product has been confirmed from SEM, TEM analysis. Again the phase purity of the materials was confirmed by XRD, which has hexagonal structure. Also diffraction pattern of the prepared phosphor is indexed well using theoretical tools of XRD. Hence from the investigation of TL-OSL properties, it is seen that synthesized thermoluminescent materials may be a promising candidate for the irradiation of foods and seeds.
