Tungsten trioxide can be used to research and assemble a large area smart glass. But why should experts actively develop all-solid-state large-area electrochromic glass technology for building exterior walls, and finally aim at industrialization? It is mainly to meet the growing demand for building energy efficiency. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html In fact, since DEB discovered the electrochromism of WO3 in 1973, scientists have been constantly researching and exploring the electrochromic material. However, it was not until 1987 that a…

WO3 film is an inorganic electrochromic material. Also, it is an oxide film of a transition metal. The tungsten trioxide film is a cathode coloring material as well. It is necessary to apply a negative voltage to the material end to color the metal cation to a low-cost reduced state, and to be colorless in the high-valent oxidation state. Other cathode coloring materials include MoO3, NB2O5, TiO2, and the like. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html While how to judge whether…

Tungsten oxide film is an extremely important inorganic electrochromic material that can be used to prepare a smart glass window, which is a new technology of energy-saving glass. And the properties of such smart glass can be dynamically controlled. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html At present, the most popular energy-saving glass on the market is low-E glass. The surface of this glass is coated with silver and metal oxygen (nitrogen) film, which has high reflectivity for far infrared rays with…

Yellow tungsten oxide electrochromic film, or WO3 electrochromic film, is an inorganic electrochromic material that can be used to prepare electrochromic devices with good coloring properties, large viewing angle, economy, memory effect and low energy consumption.

In a word, tungsten oxide smart window is a heat…

Yellow tungsten oxide electrochromic film, or tungsten trioxide film, can be used to assemble a smart glass, which is also known as an energy-saving glass – a development direction of energy-saving building materials. So, what are the advantages of tungsten trioxide electrochromic glass? More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html Main Advantages of WO3 Electrochromic Glass 1.0 Energy saving. In the colored state, the transmittance of visible light and near-infrared light is low, which can reduce the load of air conditioning in…

WO3 film for preparing large area electrochromic device is a typical representative of the earliest and the most studied cathode electrochromic materials. However, due to the complexity of the electrochromic process of tungsten trioxide, its mechanism remains controversial. Currently, the widely accepted and applied electrochromic model is the dual injection model, which is also known as the Fanghnan model. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html Fanghnan model considers that the electrochromic mechanism of tungsten trioxide electrochromic thin film is: In the…

Yellow tungsten oxide electrochromic film can be used to prepare a large area electrochromic device, which is a well known energy-saving glass for applying in building glasses. And the performance of the prepared electrochromic device must be tested. For example, test the coloring efficiency – one of the most important performance indicators for measuring electrochromic devices. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html So what is coloring efficiency? The coloring efficiency refers to a change in the optical density of the unit…
