However, it is not encumbered by some of the restrictions connected with current night vision technology.
The cryogenic cooling systems used often mean it makes it far more expensive, bulky and less portable.
The researchers paper has now been published in theAmerican Chemical Society(ACS) journal Nano Letters.
In the future, advances could make the unit even more versatile.
As the technology is developed further, that versatility will be very important.
