Is there any LED capable of emitting 780nm? Or maybe a luminophore for letting manufactures to convert invisible 940nm into anything visible? AFAIK both answers are negative.

But converting longer wavelengths to shorter ones is always going to be difficult, so I don't think there exists a practical way to make visible light from 940nm.
