Ytterbium Oxide (Yb₂O₃) is a pale yellow powder renowned for its exceptional optical properties and role in advanced laser technologies. With a CAS number of 1314-37-0 and a molecular weight of 394.08 g/mol, this rare-earth oxide offers high purity (99.9%-99.99%) and precise control over its crystalline structure. Characterized by a melting point of 2050°C and a density of 9.17 g/cm³, Yb₂O₃ stands out for its strong absorption in the near-infrared (NIR) spectrum, making it a key component in fiber lasers and optical amplifiers.
1. NIR Optical Activity: Efficiently absorbs pump light at 980 nm and emits at 1030-1060 nm, critical for generating high-power laser beams with minimal thermal distortion.
2. High Quantum Efficiency: Low non-radiative decay allows for superior energy conversion in laser gain media, reducing power consumption in industrial cutting and medical devices.
3. Thermal Conductivity: Better heat dissipation compared to other rare-earth oxides, enabling continuous operation in high-duty-cycle laser systems.
4. Chemical Stability: Resistant to moisture and atmospheric oxidation, ensuring long-term reliability in optoelectronic components.
5. Tailored Crystallinity: Available in both amorphous and crystalline forms to suit different synthesis methods, such as sol-gel or CVD coatings.
• Fiber Lasers: Doped into silica fibers to create Yb³+-doped fiber amplifiers (YDFAs), which are essential for boosting signal strength in telecommunications and data centers.
• Solid-State Lasers: Used in Yb:YAG and Yb:YVO₄ crystals for material processing (e.g., cutting stainless steel) and scientific research (e.g., spectroscopy).
• Upconversion Materials: Combines with erbium or thulium oxides to produce anti-counterfeiting pigments and biomedical imaging agents that emit visible light under NIR excitation.
• Optical Glass: Improves refractive index and thermal stability in specialty glasses for lenses and prisms in aerospace and defense optics.
• Catalysis: Acts as a support material for catalysts in hydrocarbon oxidation reactions, leveraging its surface area and redox properties.
Q: What is the typical concentration of Yb³+ ions in laser crystals?
A: Concentrations range from 0.1% to 10% by weight, depending on the desired gain bandwidth and thermal management requirements.
Q: Can Ytterbium Oxide be used in ceramic 3D printing?
A: Yes, its fine particle size (1-3 μm) makes it suitable for producing dense ceramic feedstocks for additive manufacturing of laser components.
Q: How does humidity affect the storage of Yb₂O₃?
A: While it has low hygroscopicity, prolonged exposure to high humidity may cause slight agglomeration. Store in sealed containers with desiccants for optimal shelf life.
Q: Are there any radiation safety concerns with Ytterbium Oxide?
A: No, Yb³+ ions do not emit harmful radiation; the material is classified as non-radioactive and safe for industrial handling.
Q: What is the lead time for custom purity grades?
A: Custom orders typically take 2-4 weeks, depending on the required purity level (up to 5N) and quantity.
