Cerium Gadolinium (CeGd), often referred to as Gadolinium-Doped Ceria (GDC), is a highly effective material used in the fabrication of functional oxide thin films. As a sputtering target, CeGd offers superior ionic conductivity and chemical stability, making it ideal for advanced energy systems, particularly solid oxide fuel cells (SOFCs) and gas sensors.

What is Cerium Gadolinium (CeGd) Oxide?

Cerium Gadolinium oxide is a mixed oxide material where gadolinium ions (Gd³⁺) are doped into the cerium oxide (CeO₂) crystal lattice. This doping enhances the oxygen ion conductivity by creating oxygen vacancies in the lattice structure, which is key for many high-temperature electrochemical applications.

The CeGd sputtering target is typically used to deposit thin films of GDC (Gd-doped ceria), which serve as electrolytes or buffer layers in various electrochemical and catalytic devices.

Key Properties of CeGd Sputtering Targets:

• High ionic conductivity at intermediate temperatures

• Excellent chemical and thermal stability

• Tailored Ce:Gd ratios (e.g., Ce₀.₉Gd₀.₁Oₓ or Ce₀.₈Gd₀.₂Oₓ)

• Smooth film deposition with uniform stoichiometry

• Strong adhesion to ceramic and metal substrates

Applications of CeGd Thin Films:

1. Solid Oxide Fuel Cells (SOFCs)
   CeGd is used as an electrolyte or interlayer to reduce operating temperature and improve efficiency and longevity of SOFC systems.

2. Gas Sensors
   The material’s oxygen-ion conductivity makes it ideal for oxygen and hydrocarbon sensors used in environmental monitoring and industrial automation.

3. Catalysis and Surface Engineering
   GDC coatings improve catalytic activity and thermal resistance in harsh environments, including automotive and aerospace applications.

4. Oxygen Separation Membranes
   CeGd thin films enable high oxygen flux in membrane technologies for industrial gas processing.

Advantages of Using CeGd as a Sputtering Target:

• Stable and repeatable deposition for high-performance ceramic coatings

• Compatible with RF and DC magnetron sputtering systems

• Customizable stoichiometry and particle size

• Enables dense, defect-free films with controlled microstructure

Conclusion:

Cerium Gadolinium (CeGd) sputtering targets are essential for developing high-efficiency electrochemical devices, sensors, and catalytic coatings. With their unique combination of ionic conductivity and thermal stability, CeGd targets empower innovation in the energy, environmental, and materials industries. Whether you’re building advanced SOFCs or exploring new oxide electronics, CeGd thin films offer the functionality and durability needed for cutting-edge applications.
