Looking to learn how infrared absorbing (700-1000nm) pigment is made

  • #1
Summary:
I am interested in learning the manufacturing process for IR absorbing pigment of around 700-1000nm and if I can bring that process down to a DIY level.
Hello,

I have a kinda neat idea for using infrared absorbing (700-1000nm) pigment powder. There are definitely a number of places where it can be purchased, but it's quite expensive for me.

I'm trying to get an idea of how a substance like this is manufactured. Then I want to see if it's possible to bring that down to a somewhat DIY level. I don't mean like create a procedure where anyone can do it. I mean more like come up with a way where if I did the research and took my time I could make it. I have access to machine shops and other places like that. I'm not sure if that would be useful. I have places that I can use as labs. I'm entirely self-taught when it comes to this kind of thing. I'm not looking for anyone to just give me the answer on how to make this at my house. I'm more looking for like keywords or general ideas for where to start figuring this out.

Also, whenever I ask similar things people always say "it's cheaper to just buy blahblah". Yes, sometimes that is true, but my motivation for doing DIY variants is always to learn first and foremost and everything else is secondary. So, please, if any of you are familiar with this type of thing I'd really love for you to entertain me for a moment, haha.

Thank you!
