AB  - Yttrium niobate (YNbO4) is considered to be a self-activated phosphor with a strong emission band in the blue region originating from the NbO4 3- group, but also an effective host for various luminescent-based doping-altered applications with different rare-earth ions [1-4]. Here, (Y0.8-z,Mez)NbO4:Er,Yb (z = 0, 0.1, 0.2) phosphors with  0.05 erbium and 0.15 ytterbium as up-conversion (UC) activator and sensitizer, respectively, and different metal ions (Me) replacements of Y3+ ions that launch the host local lattice disorders, were synthesized by the traditional solid-state reaction method. The starting metal oxide precursors in the appropriate molar ratio were mixed in a ball mill at 100 rpm for 8 hours, then preannealed at 800 °C for 4 hours, and finally annealed at 1200 °C for 4 hours. The morphology of the synthesized phosphors and their particle size and shape were examined by scanning electron microscopy. X-ray diffraction measurements were used to confirm the crystal structure of samples. The emission spectra of Y0.8Er0.05Yb0.15NbO4 at room temperature under the excitation of 980 nm show green and red visible UC and near-infrared emission bands of very low intensity, which originate from energy transfer UC processes between Yb3+ and Er3+ ions and which are attributed to (2H11/2, 4S3/2) → 4I15/2, 4F9/2 → 4I15/2, and 4I9/2 → 4I15/2 transitions of Er3+ ions, respectively. The lifetime of the 4S3/2 excited energy level of Er3+ in Y0.8Er0.05Yb0.15NbO4 that depends on the host and plays an essential role in infrared to visible UC is 0.198 ms. UC mechanisms, the intensity of the UC emission, and changes in lifetime caused by different Me-ions entering the host lattice were discussed.

AB  - A promising lithium-indium-oxide (LiInO2) wide band-gap semiconductor for scintillating detection, photoluminescence, and photocatalysis [1-3] was prepared by a mechanochemical solid-state synthetic procedure that can be found elsewhere [3]. Its structure and morphology were investigated by using X-ray diffraction (XRD), scanning electron microscopy (SEM), and Raman spectroscopy. SEM images show agglomerates of relatively uniform size of around 300 nm spherical-shaped particles of LiInO2 powder, while the XRD pattern confirmed the formation of the nanocrystalline tetragonal structure withamdI /41 space group (no. 141) symmetry. Detailed vibration analysis, together with the assignments of the band modes, was performed through the best-fit match of the experimental and density functional theory (DFT) calculated Raman spectrum. Geometry optimizations and vibrational frequencies calculations were conducted using B97-1 functional correlation [4] and LanL2DZ was used as a basis set.
