“…The densities of glasses at several temperatures are shown in Figure 8. The densities of simulated glasses by ia2 potential model are near to the experimental data [18,19], but it is not acceptable because this density must be brought by the abnormal dense structure units. The densities of ia3 simulations are lower than the experimental, especially for small x compositions.…”

an improved interatomic potential model was proposed for molecular dynamics simulations of lithium borate melt/ glass systems. charge of ion was reconsidered and a new composition dependent ionic charge model was suggested. a new three-body potential model controlling B-O-B angles was also proposed. The three-body term functioned to avoid square network ring consisted of B-O bonds, without preventing the change of boron coordination number between three and four. The edge-shared tetrahedra of four-coordination boron observed in the previous simulation were cleared by applying this three-body potential model.

“…The result suggests that each element is formed independently and does not have any crystal structure. The densities of Li 2 O-B 2 O 3 glass were systematically measured by Archimedes principle 5) . The density was 2.0~2.3 g/cm 3 as shown in Table 1, and the photorefractive effect of the Li 2 O-B 2 O 3 glass scintillator measured by Spectroscopic ellipsometry (SE) was 1.48~1.55 as shown in Fig.…”

Nonlinear optics crystals are vital fundamental materials in optoelectronic technology, and also important for other fields, such as information, energy resource, medical application, etc. Lithium borate system has attracted considerable attention because this system contains many important nonlinear optics crystals, such as 2LiThis study fabricated a Li 2 O-B 2 O 3 glass scintillators with TMO (transition metal oxide) activators. The crystal structure of the fabricated Li 2 O-B 2 O 3 glass scintillators were confirmed, and experiments were conducted to study the absorption curve by density of the added activators, photorefractive effect, band-gap energy, emission spectrum and elemental composition. Also, the purpose of this study is to develop a glass scintillator with improved performance by improving on it through continued researches and experiments. Further researches on light efficiencies of the glass scintillator prepared in this study for neutron irradiation should be performed. In addition, by changing compositions for glass scintillator showing good performance, it will also be carried out to calculate compositional ratios for neutron glass scintillators and to prepare ones with best performance.

The surface tension and density of xBi2O3–(1−x)GeO2 (BGO) melts have been measured systematically from their respective melting points up to around 1480 K within 0.25≤x≤0.86. With the addition of Bi2O3, the density of this system increased smoothly with a positive curvature. Deviation of molar volume from ideality of this system melts decreased firstly, past a minimum at about x=0.4, and then increased. Partial molar volumes of Bi2O3 and GeO2 have also been calculated based on the measured density data and compared with those of a binary bismuth borate system. On increasing the content of Bi2O3, the surface tension of BGO melts increased slowly when x<∼0.40, past a maximum at about x=0.50, and then decreased rapidly. In addition, the temperature coefficient of surface tension remained positive within the lower content range of Bi2O3, changed sign from positive to negative at about x=0.38, and then was almost independent of the composition within the measured temperature range when the Bi2O3 content was increased further.
