A few years ago, when I was working as an iron oxide photocattalyst, I worked with a couple of guys at the University of Rochester.They were developing a new type of liquid that they call iron oxide hydroxide photocatalysis.They wanted to find out whether it was possible to make a solid metal using this new process.If it was, they wanted to make it solid at the same temperature.When I met them, th...
A new generation of photocatalysis devices could one day transform the way people capture, store and share digital images.
The quantum dots — tiny nanowires made of carbon and oxygen — have the potential to capture light in a way that could greatly improve the speed and quality of images, as well as to reduce the amount of energy required to carry out the process.
And the technology could eventually make the use of digital cameras and other photo equipment simpler than ever.
But how exactly can we use quantum-dot technology to do this?
A team of researchers at Imperial College London have now developed a technique for turning a laser beam into a photonic quantum dot, which allows them to generate a photo-like image.
The new work could lead to the first quantum-diamond-based quantum-photonic photocatatalyst, which could be used in the near future to replace a variety of conventional photonic devices.
“We’ve made a step forward in the way we can use the laser to create quantum dots,” said Professor Robert Brown, who led the research.
“It has been a challenge in the past to get a single photon to work as a quantum dot in a device that has to capture photons, but now we have the ability to do that, and we hope that other groups will follow.”
The quantum-electrodes used in this research can be made up of two parts, each of which can be tuned to perform a different function.
The first part is a light-emitting diode, which can operate as a laser that captures a photon in the process of producing an image.
“The laser itself is not a quantum thing, it’s a photoreceptor, so it is the part that captures photons and converts them into a wave that is sent to the photodetector,” Professor Brown said.
“This is what gives the light-receptive diode its name.”
In the second part of the quantum-disrupting process, the quantum dots are used to “electrode” a photodetermine the direction of light and convert it to a quantum bit, which is then sent back to the laser.
The team’s quantum-distributed photonic-quantum-photonucleus photonic photonic technology has been described in the journal Nature Nanotechnology.
It is the first time that the team has shown that they have developed a way to create a quantum-based photocatabolic device that can be used to generate photos.
“Photonuclei, which are all the atoms in the nucleus of a photon, have a physical structure, which makes it difficult to make a photo,” Professor John Pugh, from Imperial College, said.
In the future, the team is planning to use this technology in new devices for making optical filters and other optical components.
“We are hoping that we can make some quantum dots in a similar way, so that we could make a quantum lens, a lens for use in photonics,” he said.
“It is also important to note that these devices would be much smaller and lighter than current optical devices, which require huge amounts of power.”
Professor Brown and his team are now working to develop a technique that can turn light into a quantum particle in order to make the quantum dot.
The team will present their work at the Optical Society of America’s 2017 International Conference on Photonics (ICOP), which runs from April 10 to 14 in San Francisco.
