Lu2O3 (Lutetium (III) Oxide or Lutetium Sesquioxide) is used in ceramics, glass, scintillators, and solid stated lasers.  Lu2O3 is commonly used as an host material in making laser materials.

A couple of examples where high purity Lu2O3 was used in research leading to outstanding research results are:

Researchers at Stanford University School of Medicine published an article where they made and used Eu:Lu2O3 to create a very bright thin film scintillator for single cell radionuclide images.  They use this technique to view the metabolic properties of similar cells in real time. One of the starting materials to make this material was high purity Lu2O3

In another example where high purity Lu2O3 was employed, researchers at Clemson University grew single crystals of Lutetia via hydrothermal crystal growth techniques.  Some of the materials were doped with laser active ions and they were then studied using spectroscopic techniques.  The thermal conductivity of the crystals was also investigated.
