I have in my hands a little credit card sized piece of plastic which has a little square of a substance painted in the centre. You charge up the substance in daylight for a few seconds and then it emits light in the visible spectrum when expose to an IR source like a TV remote control.
As the remote control is activated the substance flashes.
I think it may be some kind of fluorescent powder/ink but the ones I have found are hugely expensive.
What do you folks think is being use as the IR/Visiblr converter?
TIA
