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.
Claims (6)
1. A nanoparticle comprising:
monoclinic lutetium oxide; and
a rare earth dopant;
wherein the nanoparticle is free of cubic lutetium oxide.
2. The nanoparticle of claim 1 , wherein the dopant is ytterbium, holmium, or europium.
3. The nanoparticle of claim 1 , wherein the nanoparticle is at most 100 nm in diameter.
