“…At the same time, understanding the processes of interaction of ionizing radiation on semiconductor devices, as well as microelectronic devices, is very important for the design and development of electronic devices, and therefore, much attention has been paid to this area in recent years [ 8 , 9 , 10 ]. Note that while the processes of radiation damage are fairly well understood in binary oxides and halides [ 11 , 12 , 13 , 14 , 15 , 16 , 17 ], the situation in multicomponent glasses is still far from detailed [ 18 , 19 , 20 ].…”

This article considers the effect of MoO3 and SiO additives in telluride glasses on the shielding characteristics and protection of electronic microcircuits operating under conditions of increased radiation background or cosmic radiation. MoO3 and SiO dopants were chosen because their properties, including their insulating characteristics, make it possible to avoid breakdown processes caused by radiation damage. The relevance of the study consists in the proposed method of using protective glasses to protect the most important components of electronic circuits from the negative effects of ionizing radiation, which can cause failures or lead to destabilization of the electronics. Evaluation of the shielding efficiency of gamma and electron radiation was carried out using a standard method for determining the change in the threshold voltage (∆U) value of microcircuits placed behind the shield and subjected to irradiation with various doses. It was established that an increase in the content of MoO3 and SiO in the glass structure led to an increase of up to 90% in the gamma radiation shielding efficiency, while maintaining the stability of microcircuit performance under prolonged exposure to ionizing radiation. The results obtained allow us to conclude that the use of protective glasses based on TeO2–WO3–Bi2O3–MoO3–SiO is highly promising for creating local protection for the main components of microcircuits and semiconductor devices operating under conditions of increased background radiation or cosmic radiation.

“…In the past, several studies on oxide gallo-germanate glasses have been reported due to their potential use in photonics. The properties of this kind of glass have been explored in Ga 2 O 3 –GeO 2 –BaO [ 1 ], Ga 2 O 3 –GeO 2 –BaO–K 2 O [ 2 ], Ga 2 O 3 –GeO 2 –La 2 O 3 –BaO [ 3 , 4 ], and Ga 2 O 3 –GeO 2 –BaO–La 2 O 3 –Y 2 O 3 [ 5 ] systems, demonstrating that gallo-germanate glasses offer wide optical transparency (∼6 µm), low phonon energy (~850 cm −1 ), and a high linear and nonlinear refractive index [ 6 ]. Moreover, gallo-germanate glasses are mechanically resistant and chemically stable, which allows their use in the production of fibers and waveguides [ 7 , 8 , 9 ].…”

The Effect of Fluorides (BaF2, MgF2, AlF3) on Structural and Luminescent Properties of Er3+-Doped Gallo-Germanate Glass

et al. 2022

The effect of BaF2, MgF2, and AlF3 on the structural and luminescent properties of gallo-germanate glass (BGG) doped with erbium ions was investigated. A detailed analysis of infrared and Raman spectra shows that the local environment of erbium ions in the glass was influenced mainly by [GeO]4 and [GeO]6 units. Moreover, the highest number of non-bridging oxygens was found in the network of the BGG glass modified by MgF2. The 27Al MAS NMR spectrum of BGG glass with AlF3 suggests the presence of aluminum in tetra-, penta-, and octahedral coordination geometry. Therefore, the probability of the 4I13/2→4I15/2 transition of Er3+ ions increases in the BGG + MgF2 glass system. On the other hand, the luminescence spectra showed that the fluoride modifiers lead to an enhancement in the emission of each analyzed transition when different excitation sources are employed (808 nm and 980 nm). The analysis of energy transfer mechanisms shows that the fluoride compounds promote the emission intensity in different channels. These results represent a strong base for designing glasses with unique luminescent properties.

“…There is a very extensive literature on tellurite glasses doped with Er 3+ ions [ 17 ], Ho 3+ , and/or Tm 3+ ions [ 7 , 18 , 19 ]. Such glasses are suitable for IR (mid-IR) phosphors when excited with 800 nm radiation [ 1 , 9 , 20 , 21 ].…”

Crystallization of Lanthanide—Ho3+ and Tm3+ Ions Doped Tellurite Glasses

In the presented work, the tellurite glasses TeO2-WO3-ZnO doped with Tm3+ and Ho3+ ions were prepared by the same glass forming method. X-ray diffraction (XRD) and differential thermal analysis (DTA) techniques were used to study the effects of the forming technology on the thermal and structural properties of the fabricated glasses. After controlled crystallization of investigated glasses, the emission in the VIS- and NIR range was determined. The effect of silver doping on emission intensity was investigated. The value of the activation energy of the glass crystallization process was determined, while the Ea value for pure TeO2 glass was much lower than for tellurite glasses TeO2-WO3-ZnO.
