“…Furthermore, if we consider melting glass as a solvent, phosphate glasses are more acceptor than silicate or borate glasses for O 2− ions [6] and have a lower tendency to crystalline formation [7]. Although they have a potential use in the fabrication of solidstate lasers and as potential cathode materials in Li-ion batteries [8,9], the partly low chemical stability of these glasses restricts their performance [10]. It has been observed that the addition of some TMOs or alkali and alkaline earth oxides into the glass structure can improve the chemical stability of the composition [11,12].…”

The purpose of this investigation is to study dc conductivity in glass systems with a combination of 40P 2 O 5 _xV 2 O 5 _(35-x)MoO 3 _5CaO_20Li 2 O. The specimens were prepared by the conventional melt-quenching technique. The dependence of the dc conductivity on temperature and the initial concentration of samples was evaluated, and it was observed that it increases with an increase in temperature for all samples. As the vanadium oxide percentage increased, the dc conductivity also increased, and the activation energy decreased almost uniformly. Variations of activation energy and conductivity are compatible with theoretical concepts. The conductivity of these samples is mixed electronic-ionic conduction, but because of variation in the transition metal oxide concentration, electronic conductivity is more effective as a result of small polaron hopping. Also, the differential scanning calorimetry measurements of these glasses (a heating rate of 10 °C Min −1 ) were investigated, and glass transition temperatures (T g ) were determined for each chemical composition. It was shown that the enhancement of MoO 3 concentration leads to a decrease in T g values.

Iron ion-doped glasses were prepared using a melt quench method by varying lithium carbonate with Fe 2 O 3 . The prepared glasses have remarkable density and refractive index values. Hruby's criteria value, such mechanical properties as microhardness, coefficient of friction, specific wear rate, and specific wear energy values varied significantly as the load on the glass increased and morphological studies measured the efficacy of the glass samples in Bio implantation and scaffold applications. The optical band gap values decrease with an increase in concentration levels of dopant and these band gap values classify these samples under semiconductors. The transmission spectra of these glass materials resolve their utility as optical bandpass filters in the visible region.
