La2O3-CeO2 nanopowders with different La2O3 (0-20 mol%) were prepared by the sol-gel method. The modification of the cubic structure of ceria by substituting La3+ for Ce4+ into the lattice of CeO2 has been investigated. The crystal structure of La2O3-CeO2 nanomaterials.

La2O3 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. La3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of La–O bond distances ranging from 2.37–2.74 Å. There are two inequivalent O2- sites.

Apr 2, 2024 · La 2 O 3 is considered one of the most desirable oxide semiconductors due to its unique chemical and physical properties. It has a wide band gap of 5.5 eV, is thermally stable and non-toxic,...

La 2 O 3 is used to make optical glasses, to which this oxide confers increased density, refractive index, and hardness. Together with oxides of tungsten, tantalum, and thorium, La 2 O 3 improves the resistance of the glass to attack by alkali.

Jan 27, 2004 · The properties and applications of Lanthanum oxide (La2O3) or lantahana are briefly described.

Oct 21, 2024 · Among all rare earth metal oxides, lanthanum oxide (La2O3) is recognized as having a relatively lower cost compared to other rare earth oxides (e.g., Lu2O3, Gd2O3) and as being an excellent host lattice for luminescent ions.

La2O3 crystallizes in the trigonal P321 space group. The structure is three-dimensional. La3+ is bonded to six equivalent O2- atoms to form a mixture of distorted edge, face, and corner-sharing LaO6 pentagonal pyramids. There are three shorter …
