WO₃ (Tungsten Trioxide) pellets are high-purity evaporation materials used in physical vapor deposition (PVD) processes, such as thermal and electron-beam evaporation. Tungsten trioxide is well-known for its electrochromic properties, chemical stability, and optical characteristics, making it highly useful in a variety of thin-film applications.

Key Applications:

• Electrochromic Devices: WO₃ is commonly used in smart windows and displays that change color or opacity when exposed to electrical voltage.
• Gas Sensors: WO₃ thin films are used in gas sensors, particularly for detecting toxic gases like nitrogen dioxide (NO₂).
• Optical Coatings: WO₃ is applied in optical coatings due to its high refractive index and ability to function in UV, visible, and infrared spectra.
• Photocatalysts: WO₃ is used in environmental applications as a photocatalyst for splitting water under sunlight to produce hydrogen.
• Battery Materials: Tungsten trioxide has been investigated as a potential cathode material in lithium-ion batteries.

Features:

• Electrochromic Properties: WO₃ can change color and transparency when voltage is applied, making it ideal for smart window applications.
• High Refractive Index: WO₃ thin films provide superior optical performance in applications requiring high refractive index materials.
• Environmental Durability: WO₃ films exhibit good chemical and thermal stability, ensuring durability in harsh environmental conditions.
• Photocatalytic Activity: WO₃ is capable of breaking down pollutants and splitting water for hydrogen production when exposed to UV light.
