MIT engineers developed a new way to create these arrays, by scaffolding quantum rods onto patterned DNA. Using scaffolds of folded DNA, engineers assembled arrays of quantum rods with desirable photonic properties that could enable them to be used as highly efficient micro-LEDs for televisions or virtual reality devices.

Flat screen TVs that incorporate quantum dots are now commercially available, but it has been more difficult to create arrays of their elongated cousins, quantum rods, for commercial devices. Quantum rods can control both the polarization and color of light, to generate 3D images for virtual reality devices.

Using scaffolds made of folded DNA, MIT engineers have come up with a new way to precisely assemble arrays of quantum rods...

Researchers report the synthesis of semiconductor ‘giant’ core-shell quantum dots with record-breaking emissive lifetimes. In addition, the lifetimes can be tuned by making a simple alteration to the material’s internal structure.

A new study involving researchers at the University of Illinois Chicago achieved a milestone in the synthesis of multifunctional photonic nanomaterials.

The group, which included collaborators from Pr...

Finding paves the way for new generation of opto-electronic applications. Quantum dots are clusters of some 1,000 atoms which act as one large ‘super-atom’. It is possible to accurately design the electronic properties of these dots just by changing their size...

Researchers have designed smart, colour-controllable whitelight devices from quantum dots – tiny semiconductors just a few billionths of a metre in size – which are more efficient and have better colour saturation than standard LEDs, and can dynamically reproduce daylight conditions in a single light.

The researchers, from the University of Cambridge, designed the next-generation smart lighting system using a combination of nanotechnology, colour science, advanced computational methods, electronics and a unique fabrication process.

The team found that by using more than the three primary lighting colours used in typical LEDs, they were able to reproduce daylight more accu...
