Transparent heat-shielding material excellent in infrared-blocking properties and transparent heat-shielding film made of the same

摘要

A transparent heat-shielding material having a chemical formula CsXNYWO3-ZClC, characterized by being co-doped with elements of different groups in the periodic table, wherein Cs is cesium; N is tin (Sn) or antimony (Sb) or bismuth (Bi); W is tungsten; O is oxygen; and X, Y, Z, and C are positive numbers satisfying the following conditions:
X≦1.0, Y≦1.0, Y/X≦1.0, Z≦0.6, and C≦0.1;

the transparent heat-shielding material is used to make a highly transparent and highly effective heat-shielding film which can be adhered to glass panels of buildings and automobiles to block infrared radiation in the wavelength range of 800-2000 nm, thereby insulating heat and saving energy; and the film is also applicable as a composite substrate for electronic components.
