“…The thermoluminescence characteristics of various rare-earth-doped glasses for highdose gamma dosimetry purposes have been studied in recent years [97][98][99][100][101][102][103][104][105][106][107][108][109][110][111]. Scientific research has mainly been focused on extending the saturation limit of dopants in glass matrixes and improving their dosimetry features by varying their composition and concentration.…”

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.

“…Also, 7 wt% high-purity (>99.90%) amorphous B 2 O 3 powders (~10 μm) were added to SiO 2 powders to enhance the densification of the samples, followed by milling for more than 4 h. The same method was used to investigate the effect of rare earth oxides on the stability of SiO 2 glass in previous work. 15 Subsequently, 8.5 mol% TiO 2 , ZrO 2 , HfO 2 , MoO 3 , or WO 3 , or 4.25 mol% V 2 O 5 , Nb 2 O 5 , Ta 2 O 5 , or Cr 2 O 3 powders were added in the mixed SiO 2 and B 2 O 3 powders, respectively. Table 1 summarizes the crystal system, purity, and particle size of the various transition metal oxides.…”

To investigate the effect of transition metal oxides on the evaporation characteristic of SiO 2 glass at 1700°C, nine transition metal oxides were added to SiO 2 glass. The results show that V 2 O 5 , MoO 3 , and WO 3 have little effect on the high-temperature stability of SiO 2 glass due to their evaporation at 1500-1700°C. Besides, Nb 2 O 5 and Ta 2 O 5 reduce the evaporation of SiO 2 by covering the surface of the sample. Moreover, by improving the content of cristobalite, the evaporation of the SiO 2 -Cr 2 O 3 sample decreases. Meanwhile, TiO 2 , ZrO 2 , and HfO 2 are beneficial to decreasing the evaporation of SiO 2 glass because Ti, Zr, and Hf diffuse into c-SiO 2 . Meanwhile, the SiO 2 -HfO 2 sample possesses the least evaporation.

“…26 The role of different metal ions, including rare earth metals, has been studied and shown a big improvement in the glass quality. 26 Previous degradation study of the glasses shows that diffusion of alkali ions behave in a coupled fashion, as observed in a few cases where sodium is coupled to calcium. 27 Fresh active surfaces of the glass could be created by polishing, indentation, or fracture generation.…”

“…Surface indentation study of crystalline SiO 2 wafer and its amorphous form shows enhanced degrading behavior in a humid environment and reduced degradation in an alcoholic environment 25 . Another important aspect of the stability of the glass is the composition of the added modifiers, which actively determines the quality and glass properties 26 . The role of different metal ions, including rare earth metals, has been studied and shown a big improvement in the glass quality 26 .…”

Surface and subsurface alterations in freshly fractured and corroded soda‐lime float glass

We have investigated the corrosion behavior of the soda‐lime silicate float glass on freshly created active surfaces. The process of ion diffusion and ion exchange during surface corrosion is explained at the initial stages. We have reported a unique subsurface activity in the glass, which achieves equilibrium. This varies at the subsurface depth level of ≈ 10–30 nm and is visible as a broad peak in the elemental depth profile. The prolonged corrosion and heating process assists surface relaxation of the glass samples. We have observed the formation of active nucleation sites for the corrosion process on the surface. In this study, we report that the sodium ions and its corrosion compounds are decoupled from other metal ions present in the glass during diffusion relaxation and ion exchange. A combination of time of flight secondary ion mass spectrometry (TOF‐SIMS) and energy dispersive X‐ray (EDX) microanalysis help to explain the evolution and quantify the changes at the initial stages in the freshly formed glass surface.
