Antimony Tin Oxide Nanoparticle Coating Helps Create Smart Windows Blocking Infrared Rays



One of the biggest reasons why Antimony Tin Oxide nanoparticles has been in the news lately is due to one of the groundbreaking usages deciphered by a team of researchers.

Antimony tin oxide nanoparticles have been recently used by a ground of researchers to develop that they are calling as Smart glass! A glass that blocks the infrared rays of the sun. This glass will help create windows that are apt for tropical regions where the heat is at its peak.

So how were the researchers able to achieve this geneius application ? They fine tuned the chemical composition of nanoparticles.

Carbon emission reduction is one of the major benefits from the application of this coating. It is widely known that glass windows are a gateway to trapping heat and with the glass letting in more than just the light (infrared rays), the insides of the building suffer the greenhouse effect.

This problem has been persistent in tropical regions.

The Advantage

An idea that saves energy and protect us from harmful rays is a move widely welcome. Developing these windows coated with antimony tin oxide nanoparticles will help in reducing the energy consumption of a commercial complex where air conditioning is the major energy consuming attribute. The energy costs will be certainly reduced and as a resultant of the same so would be carbon emission.

The Element

The coating has been prepared by a technology institute where they initially coated the window glass with tin oxide nanoparticles that were doped with small amounts of antimony. Antimony is an alloy that is used in making batteries, glass, enamel and flame-proof material. This element when combined with tin oxide nanoparticles in certain proportions has the ability to absorb near-infrared radiation. This will help block out almost up to 90% of the infrared radiation that enters through the glass, with approximately 80% of visible light.

Though the antimony doped tin oxide nanoparticles are available commercially, the difference between those and the ones developed by the institute is that, their infrared shield coat has been prepared with a 10-nanometer antimony tin oxide nanoparticle. The nanoparticle size does matter and this figure has helped prove the recently developed coating as more profound that the existing commercial ones.

The figures speak for themselve as the infrared shielding from the institutes antimony tin oxide nanoparticle shielding is twice than that of the commercial ones that have a larger particle size.

The team was able to synthesize the antimony using a heat synthesis technique called the solvothermal method. This allows synthesis at a lower temperature as well, enabling the particles to work in a controlled manner. This feature is what helped the researchers to control the wavelengths of the light.

The research has certainly attracted attention of various investors from the particular industry. In fact, local glass companies are interesting in licensing this technique to develop the smart glass window and help deliver a more substantial product.
