Study of Thermoluminescence of Europium Doped Barium Sulphate

Investigation of Thermoluminescence Properties of Europium Doped Barium Sulphate Nanocrystals

Abstract

Nanocrystalline barium sulfate doped with europium (BaSO4Eu) was effectively ready by the synthetic co-precipitation method and its thermoluminescence (TL) dosimetry attributes were read for gamma radiation. At first the dopant (Eu) fixation was differed, beginning from 0.05 mol to up to 1.00 mol, and it was tracked down that the nanophosphor BaSO4Eu with the dopant centralization of 0.2 mol included the most noteworthy affectability inside the given parcel. The nanophosphor was additionally enhanced for its toughening temperature to get the best outcomes and was from that point tried for its reusability and blurring highlights. Further the nanophosphor was contrasted and the financially accessible standard TL dosimeter material LiFMg,Ti (famously alluded to as TLD-100) and it was tracked down that the nanophosphor not just had a higher TL affectability contrasted with the standard material over a wide scope of portions yet additionally had a TL reaction which was direct even past the portion of 1 kGy. Linearity in TL reaction to up to such high dosages (~1 kGy) is run of the mill of nanocrystalline TL phosphors. Every one of the examples were illuminated by Co-60 source (having 1.25 MeV normal energy) of gamma radiation. To test the energy autonomy of the nanophosphor (a significant trait of an optimal TL dosimeter) further examinations are being completed to inspect the reaction of the nanophosphor to ionizing radiations of various energies.
