“…Therefore, the increase in bulk modulus with ZnO content in the aluminum sodium diborate glass network led one to conclude that Zn 2+ ions try to form ring structures in the form of regular ZnO 4 tetrahedral coordination as a network former [16], and compensate for the decrease in the average coordination number of boron atoms (the decrease in N 4 values). Such an increasing bulk modulus-volume relationship was observed in some other types of glasses [17,18,64].…”

“…Furthermore, the presence of the band at around 500-530 cm −1 indicates the presence of ZnO as tetrahedral ZnO 4 units [4,17,37,47,49] which confirms that ZnO prefers to act as a network former. Fig.…”

“…In fact, the results of oxygen molar volume obtained in Table 2 are in conflict with this assumption because its nearly constant trend with the increase of ZnO content from 0 to 35 mol% indicates that there is not much creation of NBOs [35]. This leads one to conclude that Zn 2+ ions do not act as network modifier but are ratherintroduced as network former in the form of ZnO 4 units [14,[16][17][18] which compete with the B 2 O 3 (the basic glass former) for the oxygen atoms supported by the Na 2 O ions.…”

“…Some studies and reports on binary alkali borate glasses are available in literature [10][11][12], which show that there is a correlation between elastic properties and borate glass structure. In ZnO-B 2 O 3 [13,14], ZnO-B 2 O 3 -Fe 2 O 3 [15], ZnO-V 2 O 5 -B 2 O 3 [16], Li 2 O-ZnO-B 2 O 3 [17], Na 2 O-ZnO-B 2 O 3 [18], and ZnO-PbO-B 2 O 3 [19] glass systems, ultrasonic velocities and the elastic properties have been discussed in terms of boron coordination.…”

Mn 2+ -doped zinc borosilicate (ZBSM) glass thin films were first synthesized by sol-gel method. In the experiment, a thin gel film was deposited onto quartz glass substrates by dip-coating method and then heat-treated to form a Mn 2+ -doped zinc borosilicate glass thin film. Long lasting phosphorescence (LLP) and photo-stimulated long lasting phosphorescence (PSLLP) were found in the film sample. According to fluorescence spectra, LLP emission spectra, and PSLLP emission spectra, both LLP and PSLLP emissions are attributed to the energy level transition of 4 E g → 4 A 1g from Mn 2+ . Both the phosphorescence intensity decay curves contain a fast decay component and another slow decay one. The thermoluminescence (TL) spectra show that the sample has two kinds of traps at least and their energy level values are about 0.8 eV and 1.02 eV, which could be estimated by the Randall and Willcins formula. The infrared absorption spectra (IR) consist of characteristic vibration bands of Si-O-Si, Si-O-Zn, B-O in [BO 3 ], B-O group, and Zn-O in [ZnO 4 ]. Moreover, image storage and logical operation of the ZBSM film were carried out successfully through an experiment analogues of optical storage.

Glasses in the system xNd 2 O 3 •(10-x)In 2 O 3 •90Na 2 B 4 O 7 (with x＝0, 1, 3, 5 mol%) were fabricated via a melt quenching technique. The amorphous nature of the quenched glasses was confirmed by X-ray powder diffraction studies. The infrared spectra of the glasses show no boroxol ring formation in the structure of these glasses. Optical absorption of glasses shows that the transition 4 I 9/2 → 4 G 5/2 ＋ 2 G 7/2 is more intense than the other transitions, which shifts from 580 nm (for the free Nd 3＋ ion ) to 584 nm. The peak in fluorescence spectra for x＝5 mol% Nd 3＋ in the region 800-900 nm under excitation wavelength 584 nm was attributed to 4 F 3/2 → 4 I 9/2 transition. Differential thermal analysis for (x＝5 mol% Nd 3＋ ) shows glass transition (ca. 600 ℃) and crystallization temperatures (ca.1155, 975 ℃). The scanning electron microscopy studies indicate the amorphous state of glass sample.
