“…The existence of fundamental constituents like oxygen (O), uorine (F), zinc (Zn), europium (Eu) and cerium (Ce) in the synthesized glassy matrices were corroborated by the energy dispersive X-ray analysis. Nevertheless, it is far tough to recognize and calibrate accurately tiny elements like lithium and boron by nature of their smaller energy and the limitation on the identi cation extent of the EDAX analysis of the elements with atomic weight smaller than ten [14].…”

A series of singly and doubly Ce3+ / Eu3+ doped lithium borate (LBZ) glasses have been synthesized via melt quenching. XRD and SEM analysis confirmed the non-crystalline nature of glasses. The emission spectrum of Ce3+: LBZ glass reveals an extensive blue emission band at 447 nm (5d→4f) by exciting with 350 nm. An intense excitation band noticed at 393 nm (7F0→5L6) of Eu3+ in Eu3+: LBZ glass, which is associated with the excitation wavelength of near-ultraviolet LED chip. The luminescence spectra of Eu3+ disclose a strong red emission at 612 nm (5D0→7F2) excited with 393 nm. By raising the content of Eu3+ ions, the luminescence features were embellished remarkably. However, the dazzling red emission intensity of Eu3+ was ameliorated by the insertion of Ce3+ ions in co-activated glass due to energy transmission. Spectral overlap, fluorescence studies, decay dynamics, CIE coordinates and color purity corroborated the transfer of energy from Ce3+ to Eu3+. The CIE color coordinates of the optimized (1.0 Ce3+ + 1.0 Eu3+) co-doped glass has been shifted to the white light region. In view of these spectral features, 1.0 mol % Ce3+ + 1.0 mol % Eu3+: LBZ glass could be suggested as a promising candidate for the white light applications.

“…The use of lithium has attracted the attention of researchers in different fields of study: energy storage, and optical and electronic devices [4][5][6][7][8], among others. Glass compositions containing lithium tetraborate, Li 2 B 4 O 7 , have an effective atomic number (Z eff = 7.3) close to that of human tissue (Z eff = 7.4).…”

In the present work, glass samples in the (100 − x)B2O3–xLi2O binary system, with x varying from 30 to 50 mol%, were prepared using the conventional melting and moulding method, with the main objective of evaluating the thermoluminescence response when exposing these materials to ultraviolet (UV) radiation. Complementary analysis based on density, optical absorption on the UV–visible region (UV–vis absorbance), Fourier transform infrared spectroscopy on the medium region, X‐ray diffraction, and differential thermal analysis measurements were performed. Thermoluminescence measurements of vitreous samples showed glow curves with at least one peak with a maximum temperature of ~170°C after exposure to UV radiation in the temperature range 50–250°C. Samples were also exposed to beta radiation in the temperature range 25–275°C, also showing single peaks with a maximum temperature of ~150°C.

Lithium Manganese Barium Borate glass (LMBB) was prepared using a conventional melt quenching technique. Optical absorption of the prepared glass sample was investigated over a wavelength range of 200 to 1200 nm, with two absorption peaks were found at 228 nm and 476 nm corresponding to the UV and visible region, respectively. A hardness indentation test was performed on the prepared glass to see how the Mn 3? , Li 2? and Ba 2? ions in the borate framework influence mechanical behaviour. The dielectric permittivity, dielectric loss and a.c. electrical conductivity of the glass sample were examined in the frequency range from 1 Hz to 1 MHz at 30 °C. With subsequent additions of Mn 2 O 3 , the dielectric constant observed to improve. The hysteresis loop was used to determine the retentivity and coercivity of magnetic behaviour using VSM analysis, and the result confirmed that the prepared glass has paramagnetic characteristics. The elemental analysis revealed a majority of barium, manganese and oxygen in the glass, with negligible percentage of carbon. The surface morphology of the glass was examined using a scanning electron microscope, which confirmed the amorphous nature of the specimen. The scanning electron microscopic analysis was utilized to inspect the surface morphology of the LMBB borate glass. The electrochemical property of the glass was investigated using cyclic voltammetry (CV). The specific capacitance of the glass was found to decrease from 85 to 58 Fg -1 as the current density increased with the scanning rate of 2 mV s -1 .
