Scientists from the Beijing Institute of Technology have revealed a colloidal quantum dot (CQD)-based infrared-to-visible upconverter that transforms the infrared spectrum into full color, allowing people to ‘see’ the infrared in the visible light spectrum.

The research team behind the novel invention said their upconverter can be used in eyeglasses to improve human vision and for augmented reality (AR) applications. They also reported a successful implantation of an upconverter in mice, opening the possibility of an implantable photoreceptor to repair or improve vision in human eyes.

Attempts to Convert Infrared to Full Color Face Limitations

In a published study detailing the novel, full-color IR glasses, the human eye is “inherently blind” to infrared radiation. Although IR radiation interacts with the retina, infrared wavelengths lack the energy to trigger the photoisomerization of the retinal chromophore that lets people distinguish colors. As a result, humans don’t have visual access to over half of the solar spectrum.

Still, the researchers write, “harnessing this imperceptible radiation is critical, as infrared perception unlocks a vast reservoir of inaccessible information.” For example, this added visual information enables critical functions in other animals, such as navigation in darkness or detecting predators and prey from their heat. Still, they observe that our natural visual-light spectrum vision is “utterly inadequate” to access this information that so many animals rely upon.

In their study, the researchers highlight recent advances in accessing the IR spectrum, including “ocular injectable photoreceptor-binding upconversion nanoparticles” that convert infrared light into visible emissions. Other studies have also evaluated wearable lenses with nonlinear upconversion projecting infrared-transformed visible light onto the cornea and photovoltaic nanowire networks.
