This research is to study the possibility of fabricated zinc borosilicate glass doped with neodymium trioxide (ZnO-B2O3-SiO2:Nd2O3) to be a new material candidate for TLD. TGA analysis is an analytical technique used to determine a thermal stability of materials and its fraction of volatile components by monitoring rate heat flow to and from a sample and the weight changes, as temperature is changed at a constant rate. Data obtained is used to determine temperature of transitions and melting points of substances. Glass Transition Temperature (Tg) for the glass TLD sample produced obtains are between 369.01 °C - 371.74 °C and maximum annealing and reading temperature are set to be 350 °C that are below the minimum Tg values. X-Ray Diffraction (XRD) analysis has proven the samples fabricated are amorphous. Effective atomic numbers (Zeff) are in the range of 20.44-21.60. Glass TLD samples showed good linearity with TL response and faced 45.22%-59.37% fading after 30 days. Glass TLD samples also have been tested for their reproducibility ability for 6 cycles of annealing, irradiate and reading process and the reading showed a small range of different. © Published under licence by IOP Publishing Ltd.
