Does there exist a paint which if a pulsed laser of ~1500-1600nm was fired at it it would emit visible light or IR Radation (3-5 micron)?

I have seen up-converting inks and paints but I can't find any which go as high as 1500, they seem to be 800-1000nm.

Any help would be greatly appreciated.

  • $\begingroup$ there are sensor cards and ceramic like converters which go up to 1700nm, try to search for "IR-VIS converter". So it is at least thinkable that these converter materials are available as paint. $\endgroup$ – user_na Apr 2 at 13:40
  • $\begingroup$ Edmund Scientific used to sell an "IR detector" card: About the size of a business card, the active area may have been smaller. It was coated with a phosphor of some kind. You had to "charge" it under bright light. Then, it would glow orange when it was triggered by IR radiation in some band of wavelengths. I don't remember the wavelengths, but the purpose of it was to help find the beam in an IR optical system. $\endgroup$ – Solomon Slow Apr 2 at 13:41
  • $\begingroup$ @user_na I will take a look thank you $\endgroup$ – JamesDonnelly Apr 2 at 13:50
  • $\begingroup$ @SolomonSlow I have seen this product and it fits the bill, but we need a larger, more custom area. Thank you $\endgroup$ – JamesDonnelly Apr 2 at 13:51
