Nanomaterial _films_ allow ordinary glasses to see at night The night vision goggles that are common in war movies look

Nanomaterial "films" allow ordinary glasses to see at night The night vision goggles that are common in war movies look cool, but they're a little bulky. A new achievement in the research of nanocrystals by researchers is expected to make ordinary glasses easily "transformed" into night vision goggles in the future with only a "film".

Researchers from the Australian National University and other institutions reported in the monthly journal "Nanocommunications" in the United States that they have conducted in-depth research on the propagation characteristics of light, especially the interaction between light and other objects at the nanoscale, and have developed a nano-semiconductor material with high light transmittance, in which the size of the nanocrystals is only about 1 in 500 of the thickness of a human hair.

The researchers took advantage of the material's ultra-thinness, high light transmission, and made a film that was attached to ordinary glasses to make it have night vision function. Dragomir Neshef, a professor at the Australian National University who participated in the study, said that in addition to making ultra-light and convenient night vision goggles, because this nanocrystal can transmit high-intensity light and design complex beams, it is also expected to be used to make holograms, banknote anti-counterfeiting technology, medical imaging, etc.
