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.

First claim

What is claimed is:

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.
