Abstract The present work concentrates on spectral analysis of Pr3+:lead phosphate (PPbKANPr) glasses for visible lasers and optical amplifier applications and these glasses were prepared by a melt-cast technique. Vibrational modes of PPbKANPr glasses have been analyzed through FTIR and Raman techniques. Based on the absorption spectrum and the renowned Judd-Ofelt (JO) formalism, the three JO parameters (Ω2,4,6) were calculated and then used to estimate the various radiative probabilities for ch...

Abstract The pre-K-edge feature of Ti and Fe XANES of ilmenite FeTiO3 were investigated. The electronic structure of FeTiO3 was examined based on the partial density of electronic state distribution on both local and nonlocal atoms. A strong contribution of nonlocal metal-metal intervalence electronic states of Ti and Fe pre-K-edge was observed in X-ray absorption near-edge structure (XANES) measurement. This observation agrees well with the calculated local state density. The nonlocal excitatio...

In this report, efforts were made to investigate and characterize a variety of compositions in a glass system of general formula Na3+xCrxTi2−x(PO4)3 (x = 0, 0.25, 0.5 and 0.75 mol%, designated as NCTPx) to optimize their properties for use in Na-ion batteries. Several crystalline phases such as Na3Ti2(PO4)3 (COD-4106515) (NASICON), Cr2O3 (ICSD-25781) and Cr(PO3)3 (ICSD-39410) are precipitated during the process of crystallization. The microstructures of all the glass and glass–ceramic samples ar...

Abstract Titanium dioxide nanoparticles dual doped with zinc and manganese were prepared by the single step of sonochemical method using the sonicator with 20 kHz and 750 W for 30 min. Phase structure analysis results showed that the pure anatase phase was detected for all prepared samples. TEM analysis reveals the nanosized structure with uniformity of nanoparticles. The calculated bandgap energies change to be below the typical band gap energy of bare TiO2 and single doped sample suggesting hi...

Abstract Exploring the growing phenomenon of amorphous intermediate domains at nanoscale and its application as flexible active centres in a glass anode network is decisively significant to enhance sodium-ion battery performance. The outstanding stability of nanosized h-Na3Bi and NaGe domains in the glass anode network makes it more electrochemically efficient and increases its ionic conductivity. Subsequently, improved cycle stability and rate capability of glass anode half-cell have been achie...
