Tungsten Oxide Nano-Near-Infrared Absorption Properties

Tungsten oxide nanoparticles is a kind of catalysis, stealth features, electrochromic properties, Gasochromic, photochromic, gas, superconductivity, and many other features versatile semiconductor functional materials. Although so far, related to the electrical properties of tungsten oxide nanoparticles, gas properties and photocatalytic properties have more research, but the optical properties of tungsten oxide nanoparticles and composite semiconductor nanoparticles still fresh.

As science and technology and the rapid development of social production, energy saving and environmental protection has become the focus of the world. Ordinary glass of the solar spectrum, through selective is not high, so while visible light, and is located in the near infrared region of the heat will be a substantial way through, causing the indoor temperature rises, the air conditioning and other cooling equipment of the burden bring energy waste, and year by year growth trend. Therefore, exploring new environment-friendly heat shield material is always chasing a moving target researchers, these materials have a high visible light transmittance, and can effectively shield the sunlight in the near-infrared. The main application of transparent thermal insulating material with heat reflective glass and low-E glass, the former to achieve a high near infrared reflectance to achieve their goals, the latter through a highly reflective interior far infrared heat to achieve the insulation effect. However, the preparation of both complex and expensive, heat-reflective glass which also prone to cause "light pollution" and other defects.
