Abstract: Eu3+ incorporated barium borate and zinc borate glasses of composition: (35−0.50x)BaO-(65−0.50x)B 2 O 3 -xEu 2 O 3 and (50−0.50x)ZnO-(50−0.50x)B 2 O 3 -xEu 2 O 3 (x = 0–5 mol%) were synthesized by the melt quenching in the temperature range: 1200–1400 °C. Structural, thermal and optical properties of glasses were studied by X-ray diffraction (XRD), Raman spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Colorimetry (DSC), 11B Magic Angle Spinning (MAS) Nuclear Magnetic Resonance (NMR), Vickers' hardness tests, UV–visible and photoluminescence studies. The density of barium borate and zinc borate glass samples increase from 3.614 to 3.891(±0.005) g·cm−3 and from 3.393 to 3.804(±0.005) g·cm−3 respectively, upon increasing Eu 2 O 3 concentration from 1 to 5 mol%. The glass transition temperature of both series increases with increasing Eu 2 O 3 concentration. Raman and FTIR spectra show stretching and bending vibrations of B-O-B linkages in the BO 4 and BO 3 structural units. The hardness of barium borate and zinc borate glasses are 4.91(±0.21) and 4.63(±0.18) GPa respectively. The concentration of tetrahedral borons in barium borate and zinc borate glasses are 46(±1) % and 29(±1) % respectively. UV–visible spectra of glasses exhibit absorption bands due to transitions of Eu3+ from the 7 F 0,1 ground states to the excited states of Eu3+. The emission spectra of the samples containing Eu 2 O 3 were measured at an excitation wavelength of 392 nm. Glasses emit intense red light and quenching of luminescence is observed at 3 and 4 mol% Eu 2 O 3 concentration in barium borate and zinc borate glasses respectively. The emission intensity of barium borate glasses is found to be significantly higher than that of zinc borate glasses. • Comparison of density, thermal and luminescent properties of Eu 2 O 3 containing barium and zinc borate glasses. • Concentration of tetrahedral borons in barium and zinc borate glasses is 46 % and 29 % respectively. • Luminescence quenching at 3 and 4 mol% Eu 2 O 3 in barium and zinc borate glasses respectively. • Stronger red luminescence of Eu3+ in barium borate glass matrix.
