- W4315702912 abstract "Novel Sr1−xNa2xZrO3 (0 ≤ x ≤ 0.4) perovskite nanoparticles have been fabricated via the citrate-ethylene glycol sol-gel route and systemically studied. The XRD analysis shows Sr1−xNa2xZrO3 crystallized in orthorhombic structure, Rietveld refinement analysis revealed that Na ion acts positively to prevent large distortion of the perovskite, with a cell-volume contraction compared to the pure SrZrO3. Raman spectral results confirmed the existence of minor impurities. Besides, the calculated low phonon energy of 442 cm−1 makes Sr1−xNa2xZrO3 perovskite a promising host matrix for phosphor-based photonic applications. The decrease in the optical band gap (Egap) from 4.85 eV to 4.42 eV is link to the formation of localized states in the band gap due to lattice disorder and oxygen vacancies. Photoluminescence results revealed broad band emissions in the range 300–800 nm as a result of transitions involving multiple relaxation paths. The Sr1−xNa2xZrO3 perovskite is a promising candidate for phosphor host matrix." @default.
