Abstract
Single crystals have been the standard material when it comes to scintillators, but with the ability to easily be produced at a considerably lower cost and fabricated into tailored sizes and shapes there is increasing interest in the development of glass scintillators as an alternative. Ce-doped borosilicate and phosphate glasses were investigated focusing on the effect of different modifiers on their optical properties and luminescence. The borosilicate glasses were prepared aiming at the detection of thermal neutrons, utilizing B-10, while the phosphate glasses were targeting the detection of gamma-rays taking advantage of high Z elements such as, Ba, Bi, Ta, Pb and W. Structural characteristics determined by Raman spectroscopy were coupled with results from photoluminescence and UV-visible transmission measurements, while the index of refraction was estimated using the Gladstone-Dale relation using experimentally obtained density values. This work revealed barium, with its superior optical transmission and luminescent properties, to be the best high Z element for inclusion in the phosphate glasses studied.
