“…In 2007, Niederberger explained the mechanism of the sol–gel process in nonaqueous systems. Different metal oxides, such as TiO 2 , SiO 2 –GeO 2 , CeO 2 , and rare earth doped Al 2 O 3 , , are synthesized by this technique.…”

“…It can be seen in the Raman spectrum that the obvious bands are at 138, 204, 258, 398 and 461 cm À 1 . The maximal phonon energy of Sb 2 O 4 nanopowders is 461 cm À 1 , which is lower compared to those of Al 2 O 3 (phonon energy about 870 cm À 1 ) and Y 2 O 3 (phonon energy about 600 cm À 1 ) nanopowders [8,9].…”

In this paper, we report on the annealing temperature dependence of the upconversion (UC) phosphor of TiO 2 -ZnO doped with Yb 3+ and Tm 3+ . We prepared samples using metal-organic decomposition (MOD) solutions and Tm 2 O 3 powder, which were analyzed in terms of their photoluminescence (PL) spectra and crystal structures. The PL spectra showed a blue UC phosphor band at a wavelength of 476 nm. The emission intensity was greatest after annealing at 850 °C. By analyzing the crystal structures using an X-ray diffractometer (XRD), it was found that there was a large amount of RE 2 Ti 2 O 7 in the samples annealed at 900 ℃ and above.
