Introduction
Gadolinium cerium oxide sputtering targets comprise rare earth gadolinium, rare earth cerium, and oxide with the chemical formula Gd0.2Ce0.8O2. High-purity Gadolinium cerium oxide sputtering targets play a massive role in deposition processes to ensure high-quality deposited films. Gadolinium cerium oxide is also known as cerium-gadolinium oxide (CGO) or cerium(IV) oxide, gadolinium-doped. It’s used in solid oxide fuel cells (SOFCs) because it has higher ionic conductivity and lower operating temperatures than yttria-stabilized zirconia (YSZ), the material most commonly used in SOFCs.

FAQs
Answere: Gadolinium Cerium Oxide (Gd₀.₂Ce₀.₈O₂), commonly known as GDC, has excellent ionic conductivity, high oxygen ion mobility, and good thermal stability. These qualities make it an attractive material for solid oxide fuel cells (SOFCs), oxygen sensors, and catalysis, all requiring ionic transport and thermal stability.
Answere: Thin films of Gd₀.₂Ce₀.₈O₂ are widely utilized in SOFCs, oxygen sensors, and electrochemical devices. GDC thin films are significant in intermediate-temperature SOFCs, where they serve as a solid electrolyte material due to their excellent ionic conductivity and resistance to reduction at high temperatures.
Answere: Gd₀.₂Ce₀.₈O₂ sputtering targets are compatible with various physical vapor deposition (PVD) techniques, including RF and DC magnetron sputtering. The choice of technique depends on the desired thin-film quality and application. RF sputtering is commonly used for materials like GDC to ensure uniform and dense films.
Answere: The main challenge in sputtering Gd₀.₂Ce₀.₈O₂ is maintaining the desired stoichiometry of the film, as the loss of oxygen during deposition can affect its ionic conductivity. Controlling the oxygen partial pressure throughout the sputtering process and post-deposition annealing can aid in achieving the desired phase and material parameters.
Answere: Gd₀.₂Ce₀.₈O₂ can be sputtered onto various substrates, including yttria-stabilized zirconia (YSZ), alumina and silicon, depending on the specific application. The choice of substrate influences the adhesion, microstructure, and crystallinity of the deposited GDC thin films, which are critical for applications like fuel cells and oxygen sensors.
