A search for a special material

[Ariellev]

Hi all,
I am in a search for a material that is transparent in UV wavelengths, but reflect light in the visible wavelength (e.g. the opposite of standard glass). does anyone here know of such a material?

Thank's in advance

Some metals can do this, if the plasma frequency is right.

I think Teflon/PTFE transmits UV light.

I'll check them! thanks allot!
any more?

for your help!

Hello,

Thank you for reaching out to the scientific community for help with your search for a special material. I am a scientist specializing in materials science and I may be able to assist you.

Based on your description, it sounds like you are looking for a material with selective reflectivity, which means it reflects certain wavelengths of light while allowing others to pass through. This type of material is commonly used in applications such as optical filters and coatings.

One potential material that fits your criteria is called titanium dioxide (TiO2). It is commonly used as a white pigment in paints and coatings, but it also has unique optical properties that make it suitable for your application. It is transparent in the UV range and has a high refractive index, which causes it to reflect visible light.

Another material that may be of interest is called zinc oxide (ZnO). Like TiO2, it is transparent in the UV range and has a high refractive index. It is also used in a variety of applications such as sunscreen and optical coatings.

I hope this information helps in your search for the perfect material. If you have any further questions or need more assistance, please don't hesitate to reach out.

Best of luck in your research!

Sincerely,
