Nano-Tungsten Oxide Thin Films Photoluminescence Application(b)

Photochromic properties of tungsten oxide in the optical information storage, optical control, field optical switches, optical device materials, optical information such as genetic material has broad application prospects. Using photochromic properties of tungsten oxide system has been designed, and creating a lot of practical applications of the device, such as can be used to split water WO3 / TiO2 composite solar cells while having photochromic properties of wisdom electrochromic window (PV-ECsmartwindows).

Dye-Sensitized Solar Cell

Dye-sensitized solar cell (DSSC) refers to the dye-sensitized nanostructured porous anodic film is a light, according to the principle of photovoltaic, solar energy directly into electrical energy in a semiconductor optoelectronic devices. Photoelectric conversion efficiency and a light film of the band gap of the anode of a great relationship, generally select the band gap of 3.2eV of TiO2 films as photoanode. WO3 with TiO2 has a similar band structure, but its band gap

Is relatively small, but the power of tungsten oxide dye-sensitized solar cells is sufficient to drive the use of tungsten oxide thin film electrochromic smart windows made color characteristics, such as electrochromic display devices. And so while using tungsten oxide photochromic - electrochromic device features a relatively simple in structure, green.

UV Film

Tungsten oxide sensitive to ultraviolet light, and therefore can be made into a film, coated on the windows to prevent ultraviolet damage to human body. If in the sunglasses plated tungsten oxide film, the light intensity when the automatic color UV shielding reducing UV damage to the human eye. Also tungsten oxide can also be used to detect whether there is presence of ultraviolet light and the intensity of ultraviolet size.
