Nanometer vanadium dioxide (VO₂) provides optimized phase-transition properties, superior infrared modulation, and enhanced thermal stability. Designed for advanced applications, it ensures efficient material integration, extended durability, and high-performance adaptability.
Product Overview
Nanometer Vanadium Dioxide (VO₂) is a material with remarkable thermochromic properties, specifically exhibiting a metal-to-semiconductor phase transition. The phase transition temperature of pure VO₂ is around 68°C, at which it undergoes a transformation from metal to semiconductor. Tungsten-doped VO₂ significantly reduces this transition temperature to approximately 25°C. VO₂ also demonstrates notable changes in mid-infrared light transmittance, showcasing excellent phase-change light-switching capabilities. This material has broad applications in smart windows, laser protection, and optical data storage.
Key Features
- Thermochromic Properties: VO₂ undergoes a metal-semiconductor transition within a specific temperature range, resulting in noticeable optical performance changes.
- Tungsten-Doped Modification: The doping of tungsten lowers the phase transition temperature to near room temperature, enhancing its performance in low-temperature applications.
- Superior Phase-Change Light-Switching Performance: VO₂ demonstrates significant variations in infrared transmittance under high and low-temperature conditions, ideal for applications such as smart windows and other high-performance optical materials.
- Nanometer Particle Size: With a particle size of 30-50nm, VO₂ exhibits a large surface area, improving its optical, thermal, and electrical properties.
Applications
- Smart Windows: Utilizes its phase-change characteristics to adjust light transmittance, enabling temperature-adaptive regulation for energy-efficient and eco-friendly windows.
- Laser Protection Films: Serves as a protective layer for laser protection, effectively blocking harmful laser radiation and safeguarding both equipment and personnel.
- Infrared Detection: Acts as a material for infrared detection, capable of responding to varying infrared radiation due to temperature changes.
- Optical Data Storage: Used in optical storage devices, enabling temperature-controlled data storage and retrieval.
- High-Performance Optical Sensors and Switches: Incorporated into advanced optical switches and sensors, optimizing their efficiency and intelligence.
