Abstract
A nanoparticle containing monoclinic lutetium oxide. A method of: dispersing a lutetium salt solution in a stream of oxygen gas to form droplets, and combusting the droplets to form nanoparticles containing lutetium oxide. The combustion occurs at a temperature sufficient to form monoclinic lutetium oxide in the nanoparticles. An article containing lutetium oxide and having an average grain size of at most 10 microns.
Claims3
A nanoparticle comprising:
- monoclinic lutetium oxide;
- and
- a rare earth dopant;
- wherein the nanoparticle is free of cubic lutetium oxide.
