일반 설명

La2O3 is a wide band gap p-type semiconductor with an empty Ln-4f shell and is widely used to prepare optical materials, dielectrics, and conductive ceramics. La2O3 can also be used as a catalyst in many organic transformations.

애플리케이션

Lanthanum(III) oxide can be used as a dopant to prepare radiation-shielding glasses. For example, it can be added to waste soda-lime glass to improve the linear attenuation coefficient and radiation shielding characteristics of the glass.

It can be used as a recyclable catalytic system for the synthesis of diphenyl sulfides and selenides and for the C-N cross-coupling of aryl halides with heteroaromatic amines.

It can also be used as a promoter or support material for the selective oxidation of methanol over gold catalyst.
Precursor to LAMOX fast ion conductors and superconductors.

특징 및 장점

  • High refractive index
  • Low dispersion
  • Colorless in the glass matrix
  • Efficient, inexpensive, and recyclable catalyst

Low-power-threshold cw laser-induced incandescence (CWLII) has been observed in La(2)O(3):Er(3+)-Yb(3+) phosphor on excitation by a 976 nm IR laser. It is suggested that incandescence originates from the extensive heating induced by the nonradiative processes taking place following the laser excitation.
