CsxWO3 nanoparticles, which are also known as cesium doped tungsten oxide nanoparticles or cesium tungsten bronze nanoparticles, have good near infrared absorption ability and visible light transmission properties for applying to the infrared mini light-emitting diode to reduce the intensity of over irradiated near infrared.

As a new type of functional material for producing near-infrared shielding material, CsxWO3-ZnO composite is designed to promote the practical applications of CsxWO3. You know, cesium tungsten bronze (CsxWO3) is a promising candidate for manufacturing near-infrared shielding materials on windows of buildings and automobiles. However, the near-infrared shielding ability of CsxWO3 easily deteriorates in hot humid and alkaline environments, which hinders further applications of CsxWO3.

W18O49, or violet tungsten oxide, is well-known as a near-infrared absorber because of its excellent near-infrared absorption properties. So, there is no doubt that violet tungsten oxide is popular in the application of energy-saving windows to play a role of high heat insulation. In this regard, some experts have investigated the morphology-controlled synthesis and near-infrared absorption properties of W18O49 systematically for the application of innovative energy-saving windows.

Cs-doped tungsten bronze, or CsxWO3, is a near infrared shielding material with high near-infrared absorption. Mo-doped tungsten bronze, like CsxWO3, is also a material of high near-infrared absorbing property. That is because both Mo and W belong to VIB-sub-group, and possess similar ionic radii, electronegativity and oxide lattice configuration.

Cs doped tungsten oxide nanoparticles, or CsxWO3 nanoparticles, are an important functional material for manufacturing coated glass. As CsxWO3 nanoparticles are more and more welcomed in the manufacture of coated glass, the preparation of CsxWO3 nanoparticles also attract much attention. It has been reported that hexagonal CsxWO3 nanoparticles can be fabricated by a newly developed simple two-step route.

Cs doped tungsten oxide nanoparticles for producing functional film may be Cs0.32WO3 nanoparticles with excellent near-infrared shielding ability. However, there are still some critical issues for industrial applications, such as, photochromic instability - a blue color change of Cs doped tungsten oxide nanoparticles under ultraviolet irradiation. But do you know why CsxWO3 nano particles change color?

As a heat shielding material, Cs doped tungsten oxide nanoparticles are well known as cesium tungsten bronze nanoparticles, with the formula of CsxWO3. Due to the excellent near-infrared (NIR) shielding properties, Cs doped tungsten oxide nanoparticles are more and more popular in the study of heat insulation products for applying to glasses of buildings and autos. While the color of CsxWO3 nano powder changes under UV irradiation due to photochromic instability, which hinders its commercial applications. Then, how to solve the color change of cesium tungsten bronze?

Cs doped tungsten oxide nanoparticles for producing energy-efficient window can be synthesized by a simple thermal reduction method, and then further dispersed by bead milling to obtain the nano dispersion liquid of CsxWO3 nanoparticles. The nano dispersion liquid can be employed to make a unique functional film with 70% visible light transmittance and a near infrared transmittance less than 10%, while maintaining a high transparency with less than 1.0% haze.

Cs doped tungsten oxide nanoparticles for producing heat insulating glass may be Cs0.32WO3 nanoparticles with excellent NIR shielding properties. Wherein, the Cs doped tungsten oxide nanoparticles are often prepared into heat insulation film at first. And then the Cs0.32WO3 film is used for covering on an ordinary sheet of glass to obtain heat insulating glass.

Cs doped tungsten oxide nanoparticles such as Cs0.33WO3 nanoparticles are usually applied to produce highly transparent heat insulation products as a near-infrared absorber. It has been reported that the optical and dielectric properties of Cs0.33WO3 bulk crystal and nanoparticles can be investigated by high energy-resolution electron energy-loss spectroscopy (HR-EELS).
