    A breakthrough in stabilizing nanocrystals introduces a low-cost, energy-efficient light source for consumer electronic devices, detectors and medical imaging.

    Light-emitting diodes (LEDs) are an unsung hero of the lighting industry. They run efficiently, give off little heat and last for a long time. Now scientists are looking at new materials to make more efficient and longer-lived LEDs with applications in consumer electronics, medicine and security.

    Quantum Emitters: Beyond Crystal Clear to Single-Photon Pure

    September 3, 2021, Categories  Physics, Technology/Electronics

    Nanoscale luminescence quenching occurs when a focused ion beam is irradiated. By selectively quenching the uncorrelated light, one can increase the single-photon purity from the quantum emitter without optical degradation and structural destruction

    A research team has developed a technique that can isolate the desired quality emitter by reducing the noise surrounding the target with what they have dubbed a ‘nanoscale focus pinspot.’

    Photons – fundamental particles of light – are carrying these words to your eyes via the light from your computer screen or phone. Photons play a key role in the next-generation quantum information technology, such as quantum computing and communications...
