Their structure and optical properties were characterized by transmittance spectra, Fourier transform infrared spectra (FTIR), Raman spectra, excitation and emission spectra, and X-ray excited luminescence (XEL) spectra in detail. Transparency of the as-synthesized borogermanate glasses exceeds 80% in 400-800 nm regions. The cut-off edges of borogermanate glasses are in the vicinity of 308 nm, and they shift towards longer wavelength (red-shifted) with the elevated x values. Both glass density and mean molecular weight increase in a linear relationship with increasing x values. With increasing x values, the characteristic emission intensity of both Gd<sup>3+</sup> and Eu<sup>3+</sup> ions decrease progressively under 276 nm excitation, while these emission intensities seem irregular under 394 nm excitation. The strongest X-ray excited luminescence (XEL) intensity occurs at x = 35 glass sample, which is improved about 35% with comparison to the x = 20 one. Additionally, the information on glass structure is also discussed by FTIR and Raman spectra.</div></div> </li> <li class='list-group-item border-0 py-3 px-0'> <div class='row g-0 align-items-center mb-2'><div class='col-12 col-md-3 fullRecLabelEnglish fw-bold mb-2 mb-md-0'><span class='text-muted small'>Keywords</span></div><div class='col-12 col-md-9 leftDirection leftAlign'>Fourier transform spectra; Raman spectra; X-ray emission spectra; borate glasses; europium compounds; gadolinium compounds; germanate glasses; glass structure; infrared spectra; melt processing; photoluminescence; quenching (thermal); red shift; scintillation; transparency; B<sub>2</sub>O<sub>3</sub>-GeO<sub>2</sub>-Gd<sub>2</sub>O<sub>3</sub>-Eu<sub>2</sub>O<sub>3</sub>; FTIR; Fourier transform infrared spectra; Raman spectra; X-ray excited luminescence spectra; borogermanate scintillating glasses; emission spectra; excitation spectra; glass density; glass structure; luminescent properties; mean molecular weight; melt quenching; optical properties; red shift; transmittance spectra; transparency; Absorption; Energy exchange; Glass; Ions; Luminescence; Sun; Vibrations; <formula formulatype=${rm Eu}^{3+}$ -activated borogermanate scintillating glasses; Energy transfer; X-ray excited luminescence; photoluminescence;
