Cs0.33WO3 for producing transparent glass coating is known as an environmentally friendly dingal material with good near infrared absorbing property. You know, along with a growing interest in an environment, there is a demand for a method for suppressing a temperature rise in rooms and cars to increase an efficiency of an air conditioner. As one countermeasure, it is considered to form a near-infrared ray absorbing layer on the abovementioned window material to impart a heat shielding performance.
