일반 설명

Lanthanum (III) oxide is an alkaline earth oxide, and is a diamagnetic, isostructural analog of neodymium oxide. It is also an efficient recyclable catalyst, and can be used in coupling various aryl halides with aromatic/alkyl thiols.

애플리케이션

Lanthanum (III) oxide was used as an analytical standard in inductively coupled plasma atomic emission spectrometry (ICP-AES) for chemical characterization of ancient pottery.
Suitable for use as atomic absorption standard.
Precursor to LAMOX fast ion conductors and superconductors.

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.
