OSL dosimetric properties of cerium doped lutetium orthosilicates

Abstract: This paper presents selected optically stimulated luminescence properties of Lu2SiO5:Ce single crystalline films grown using Liquid Phase Epitaxy technique. Comparison of continuous wave optically stimulated luminescence decay curves under blue and green light stimulation is shown. The dose response characteristic is found to be linear in the studied range from 100 uGy to 1 Gy. Analyses of the linearly modulated optically stimulated luminescence signal enabled establishing of the photoionization cross sections for blue light (470 nm). Bleachability and thermal stability of CW-OSL signal are discussed, as well as preliminary results of the fading study.
