Nano tungsten trioxide, or WO3 nano powder, has seen application in our everyday life. For example, WO3 nanoparticles is more and more widely applied for preparing bedroom thermal insulating glass coating. And such coating is popular as it has the characteristics of high visible light transmittance and high IR shielding performance.

According to the experts, the visible light (400-700 nm) can be identified by human’s eyes. While the IR radiation that has longer wavelengths than those of visible light is generally invisible to the human eye. The data show that about more than half of the total energy from the Sun was found to arrive on earth in the form of infrared. And it is the invisible infrared that heat your bedroom in the hot summer. So, the bedroom thermal insulating glass coating of nano tungsten trioxide is a good choice for shielding the infrared to reduce your room temperature and thereby saving energy and reduce electricity costs.
