“…However, lithium-doped phosphate glasses characterize a broad TL peak at the rage of 200-300 • C [81]. On the other hand, barium-doped phosphate glasses feature at least two TL peaks, approximately at 220 and 390 • C, which are attributed to Ba 2+ ions [82]. The observed TL peaks result from various defects generated by the modifier ions (Ba 2+ and Li + ) inserted into the glass matrix.…”

Different types of ceramics and glass have been extensively investigated due to their application in brachytherapy, radiotherapy, nuclear medicine diagnosis, radioisotope power systems, radiation processing of food, geological and archaeological dating methods. This review collects the newest experimental results on the thermoluminescent (TL) properties of crystalline and glassy materials. The comparison of the physico-chemical properties shows that glassy materials could be a promising alternative for dosimetry purposes. Furthermore, the controlled process of crystallization can enhance the thermoluminescent properties of glasses. On the other hand, the article presents information on the ranges of the linear response to the dose of ionizing radiation and on the temperature positions of the thermoluminescent peaks depending on the doping concentration with rare-earth elements for crystalline and glassy materials. Additionally, the stability of dosimetric information storage (fading) and the optimal concentration of admixtures that cause the highest thermoluminescent response for a given type of the material are characterized. The influence of modifiers addition, i.e., rare-earth elements on the spectral properties of borate and phosphate glasses is described.

“…The influence of ionizing radiations (such as X-rays, γ-rays, heavy ions beams, synchrotron and UV irradiation, etc.) on structural and other properties of glasses was studied in [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]. In [35] structural changes in silica glass after electron irradiation with electrons energy 2.5MeV was studied by methods of Raman spectroscopy.…”

Structural Changes in Silica Glass under the Action of Electron Beam Irradiation: The Effect of Irradiation Dose

et al. 2021

Structural changes in silica glass, produced by electron irradiation, with electrons energies of 50 keV and doses of 5–80 mC/cm2 were studied by Raman spectroscopy in frequency ranges of 300–550 and of 700–1500 cm–1. It is shown that for irradiation doses less than 5 mC/cm2 the decrease of siloxane rings concentration in glass takes place. The further increase of dose results in the increase of siloxane rings concentration in glass network after irrsdiation. And for doses of more than 40 mC/cm2 the whole destruction of glass structure and its structural units takes place. The obtained results for silica glass were compared with similar results for crystalline quartz.

“…Формирование люминесцентных центров окраски при воздействии эксимерным KrF-лазером (λ = 248 nm) описано в работе [21]. Результаты исследования центров окраски и люминесцентных центров в барий-фосфатных и цинк-фосфатных стеклах, содержащих серебро и медь, было проведено в работах [22][23]. В то же время модификация оптических свойств стекол при комплексном рентгеновском и лазерном облучении, применительно к созданию оптической памяти, еще недостаточно изучена.…”

The results of complex X-ray and ultraviolet (UV) nanosecond laser radiations action on alkali-containing silicate glasses is presented.It is shown that under the action of X-ray radiation color centers with luminescent properties appear in glasses. This is caused by the increase of concentration of glass network structural defects. Under the action of laser radiation the destruction of these defects takes place, accompanied by the bleaching of glass and by the disappearance of luminescence. The dynamic of glass bleaching under the laser action and the influence of alkali metals ions (Li, Na, K) on this precess is studied. The mechanisms of color centers destruction by laser radiation are proposed..
