Rare-Earth Oxide Crystals & Scandate Single Crystals (Lu₂O₃, Sc₂O₃, GdScO₃, YScO₃)
We grow and supply high-temperature oxide single crystals and scandate materials for high-power photonics, oxide electronics, epitaxy substrates, and advanced research. This product family includes undoped and doped options with deliverables ranging from boules and blanks to polished wafers.
Core Materials We Support
| Crystal | Category | Common Use |
|---|---|---|
| Lu2O3 (Lutetia) | Rare-earth sesquioxide | High-power laser host, photonics research |
| Sc2O3 (Scandia) | Rare-earth sesquioxide | Optical materials, substrate research |
| GdScO3 | Scandate | Epitaxy substrate (oxide electronics, perovskite thin films) |
| YScO3 | Scandate | Epitaxy substrate, oxide electronics research |
| Related RE oxides / custom compositions | On request | Material development and specialty programs |
Doping Options
We support rare-earth dopants for optical/laser applications and can tailor concentrations by target use case.
- Typical dopants: Yb, Nd, Er, Ho, Tm, Ce, Eu, Pr (others upon request)
- Customized concentration: defined per application (laser, spectroscopy, functional oxides)
- Notes: final feasibility depends on composition, boule size, and defect/strain targets
Why These Oxides & Scandates
- High melting points and strong thermal stability for demanding photonic conditions
- Excellent candidates for high-power laser hosts (doped sesquioxides)
- Scandates as epitaxy substrates enabling controlled lattice matching for oxide thin films
Deliverable Forms
- Boules, cut blanks, or seed material (by program)
- Polished plates / windows / rods
- Polished wafers/substrates (orientation, thickness, and finish specified)
