Synthesis and TL glow curve analysis of BaSO4:Eu,Dy phosphor
The polycrystalline samples of Ba1−x−ySO4:Eux,Dyy (0≤x≤1, 0≤y≤1) have been prepared using the chemical co-precipitation technique. The thermoluminescence (TL) sensitivity of the samples have been found changing with the value of x and y and the highest TL intensity is for Ba96SO4:Eu02,Dy02. The samp...

| description | The polycrystalline samples of Ba1−x−ySO4:Eux,Dyy (0≤x≤1, 0≤y≤1) have been prepared using the chemical co-precipitation technique. The thermoluminescence (TL) sensitivity of the samples have been found changing with the value of x and y and the highest TL intensity is for Ba96SO4:Eu02,Dy02. The sample has been characterised by x-ray diffraction (XRD). The samples are found to have orthorhombic structure. For TL analysis Ba96SO4:Eu02,Dy02 is annealed at different temperatures ranging from 873 to 1173K. Kinetic parameters of all the TL glow curves of Ba1−x−ySO4:Eux,Dyy for different values of x and y and also for the TL glow curves Ba96SO4:Eu02,Dy02 annealed at different temperatures have been found out using computerised glow curve deconvolution (CGCD) method. The activation energy for the most intense TL peak at (444–453K) is found out to be 1.26eV and order of kinetics is 1.35.
► TL study of BaSO4:Eu,Dy is reported for the first time. ► The kinetic parameters are evaluated by CGCD. ► Effect of concentration, annealing temperature and dose response curve discussed. |
