“…The creation of electronic defects/excited states in the solid state by exposure to radiation is well known [4,[47][48][49][50][51]; after all the photographic industry used to be based upon this. In fact both X-ray detectors and self coloring sunglasses depend on the creation of such states.…”

“…The interaction of intense beams of synchrotron radiation based X-rays with a variety of materials has been found to alter the state of the materials. Damage is not only sustained to samples in static experiments but there is also evidence that X-ray interactions can change the dynamics [1], or even induce, structure forming processes [2][3][4][5], or influence the reaction rate of catalytic processes [6].…”

Understanding the interactions among dopant species and the role of the host lattice is of fundamental importance for the chemical formulation of optically active glasses. Here, we consider the archetypal dopant pair of Ag–Ce in complex fluorophosphate (PF) and sulfophosphate (PS) matrices, in which variable bonding environments and ligand selectivity exert distinct effects on dopant properties. The addition of Ag+ to PF glasses blue-shifts the ultraviolet (UV) cutoff wavelength of Ce3+ and enhances its photoluminescence (PL) intensity. In PS matrices, the exact opposite effect is observed: red-shifting the UV cutoff and lowering the PL intensity. No Ag–Ag pairs or cluster species were found in either matrix material; however, in PS, such clustering could be triggered by secondary broad-band UV–visible irradiation. The optical properties of Ag–Ce-codoped glasses are a result of the ionocovalent character of the Ag+–O–Ce3+ bond, the cross-relaxation process between Ag+ and Ce3+, and the redox ratio of Ce3+/Ce4+. In the PF glasses, the enhancement of the Ce3+ PL intensity is due to energy transfer from Ag+ to Ce3+ and a redox shift from Ce4+ to Ce3+. The more covalent Ag+–O–Ce3+ interactions in the PS series decrease the Ce3+/Ce4+ ratio. Moreover, photoinduced Ag clustering is facilitated in the more covalent environment, which indicates that glasses commonly used for Ag nanoparticle formation, such as silicate glasses, also possess more covalent Ag+–O bonding.

“…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.
