Other related materials: tungsten doped VO2


Properties and Main application of Vanadium Dioxide Nano Powder:

Vanadium oxide nano material has a high temperature coefficient of resistance and photothermal effect, and has potential application prospects in infrared detection. Vanadium(IV) oxide nanopowder is an excellent heat-sensitive material.

Principle of nano VO2 film infrared radiation detector:
Using the principle that the infrared radiation heat effect causes the phase change of nano VO2 , the current signal is converted into the signal of infrared radiation intensity through computer algorithm simulation and analysis, so that information such as the size of the infrared radiation flux and the radiation frequency band can be obtained.

Detectors made of nano vanadium dioxide are mainly used in the following fields:
1. Fire Alarm Device
2. Night vision goggles
3. Infrared guide
4. Navigation and positioning system


For tungsten doped vanadium dioxide (W-VO2) nano powder, it can be customized to adjust the phase change temperature. Please feel free to contact us if you have further requirements.
