Quartz yields phase
transitions at 573°C and 870°C and the structure is changing from α to β quartz
type and β-quartz to tridymite, respectively. By heating quartz samples at
increasingly annealing temperatures, phase transitions can be seen with
different methods. In this study, commercially available Merck quartz was used.
The intensity change of high temperature TL peaks (at 325°C and 375°C) of Merck
quartz was investigated by TL, CW-OSL and LM-OSL respectively; OSL measurements
were measured at both room temperature and 125°C. In order to monitor the phase
transitions and the effect of annealing temperature on luminescence intensity, the quartz samples
were annealed 1 hour between 500°C and 1000°C by the step of 50°C. When the
luminescence intensities were analyzed for different luminescence methods,
phase transition at 573°C and 870°C were observed at 600°C and 850°C. The study
indicates that annealing temperature has an effect on both TL and OSL signals.
