Li2O-B2O3 glasses were synthesized doping with TiO2 and co-doping with TiO2 as well as ZnO nanoparticles through the melt-quenching process. LB1, LBT2 and LBTZ3 were the labeling of the samples. The X-ray analysis of these glass samples have shown two amorphous halos at small values of 2θ (≈ 22o and 45o), which were due to the short-range periodicity of the glass network as a result of non-bridging oxygens (NBOs). The prominent bands exhibited in FTIR spectra were due to trigonal (BO3) and tetrahedral (BO4) structural units and as well due to bending vibrations of B–O–B linkages. The absorption bands observed in the spectra were attributed to stretching vibration modes of O-H bonds present in the moisture in the glass samples. The rigidity of the samples follows order: LBT2 > LBTZ3 > LB1. The ESR spectra of the sample LBTZ3 has shown a spectral line centered at about g≈1.94. The addition of ZnO nanoparticles into the glass matrix leads to convert the non-magnetic glass sample into a magnetic glass material; because some of Ti4+ ions may be converted as Ti3+ ions in the melt-quenching process. Thus, we expect that these materials can find potential applications such as solid state electrolytes, humidity sensors and magnetic sensors etc. |
