#2This will almost certainly be used for weapons in short order.
Currently if you want thermal imaging or very low light capability you have to use very expensive substrates. Being able to use CMOS detectors for MWIR/LWIR would instantly increase available resolutions by an order of magnitude at any given price point, assuming these filters are actually relatively cheap.

#3If I'm not misunderstanding the paper this shows extremely low quantum efficiencies-- doesn't sound like it would be useful without massive increases in QE.

Yep, if it works at all, ITAR will slap it with a "Don't even think about using this for anything" label.

Anything and everything will be used for weapons. All, from nuclear reactions ultrafast computers to water pipes and sugar.
The problem with weapons is not that science and technology allow more and more. Say, Pol Pot's regime, or the Rwanda genocide, have shown that large-scale atrocities can be perpetrated using very low-tech means.

#7Reminds me of this experiment from Ben Krasnow using thermal paint - https://www.youtube.com/watch?v=qgS0hTKBLXM

#8Years ago I stumbled upon something related: it was a piece of transparent polymer or polycarbonate that would glow when exposed to infrared light.
I tried to find it again repeatedly, but never managed to find it. Anyone knows this?

Re: Colour-changing magnifying glass gives clear view of infrared light
#10So, is this something that can actually make infrared light visible, or a coating that can be applied directly to sensors?
(I suspect the headline is simply clickbait/a lie, just like most university press releases.)
