Abstract

The PTFE was added before re-annealing treatment which the mass ratio of CaSO4:Dy and PTFE was fixed to 2:3. The re-annealing treatments of the samples were done at temperature 700 C for 1 hr. The obtained samples were characterized using a Fouriertransform infrared (FTIR) and X-ray diffraction (XRD) to observe the molecule bonding in sample and crystal properties, respectively. From the experimental results, it was observed that the thermoluminescence intensity of CaSO4:Dy, CaSO4:Dy re-annealed at 700 C, and CaSO4:Dy + PTFE re-annealed at 700 C are 57.03, 75.15, and 1191.11 nC, respectively. The intensity of 700 C-re-annealed CaSO4:Dy increased significantly after PTFE addition.
