Researchers from KU Leuven, the University of Strasbourg, and CNRS have discovered a phosphor that could make next-gen fluorescent and LED lighting even cheaper and more efficient. The team used highly luminescent clusters of silver atoms and the porous framework of minerals known as zeolites. Silver clusters consist of just a few silver atoms and have remarkable optical properties.

A research team in Japan discovered through numerical calculations that nanoparticles of transition metal nitrides and carbides absorb sunlight very efficiently, and confirmed experimentally that nitride nanoparticles, when dispersed in water, quickly raise water temperature.

RMIT quantum computing researchers have developed and demonstrated a method capable of efficiently detecting high-dimensional entanglement.Entanglement in quantum physics is the ability of two or more particles to be related to each other in ways which are beyond what is possible in classical physics.Having information on a particle in an entangled ensemble reveals an "unnatural" amount of information on the other particles.

Synopsys has announced the latest release of its RSoft Photonic System Design Suite, the company's software for the design of optical communication systems andPhotonic ICs (PICs) at the signal propagation level. Version 2016.06 introduces a new interface to PhoeniX Software's OptoDesigner chip and mask layout tool to streamline design and fabrication processes for PICs.

Researchers from the Universities of Bristol and Exeter are one step closer to developing next-gen low-cost, high-efficiency solar cells. The structure is one of the world's first examples of a tri-layer metasurface absorber using a carbon interlayer.The system, developed by Chenglong Wang a PhD student in Professor Martin Cryan's research group, uses amorphous carbon as an inter-layer between thin gold films with the upper film patterned with a ...

A European group of scientists are working on the development of a breakthrough, compact, cost-effective retinal scanner that will play a key role in targeting the early diagnosis of retinal diseases that are worldwide leading causes of blindness. Funded by the Photonics PPP platform, OCTChip is set to revolutionise diagnosis of retinal diseases and prevent millions of cases of blindness.

A smart material that switches back and forth between transparent and opaque could be installed in buildings or automobiles, potentially reducing energy bills by avoiding the need for costly air conditioning.Imagine a glass skyscraper in which all of the windows could go from clear to opaque at the flick of a switch, allowing occupants to regulate the amount of sunlight coming through the windows without having to rely on costly air conditioning ...

Australian researchers at the University of Adelaide have developed a method for embedding light-emitting nanoparticles into glass without losing any of their unique properties – a major step towards 'smart glass' applications such as 3D display screens or remote radiation sensors.This "hybrid glass" combines the properties of special luminescent nanoparticles with the well-known aspects of glass, such as transparency and the ability to be ...

An interdisciplinary team of researchers enabled by the National Science Foundation-funded Materials Research Science and Engineering Centers (MRSEC) program has developed a way to break fibers or sheets of material into many tiny, almost perfectly uniform segments or strips. The method can work on plastics, metals, glasses, and even natural materials such as silk or hair, producing sectioned particles ranging in size from nanoparticles to ones t...

Scientists from the RIKEN Center for Advanced Photonics (RAP) have, for the first time, successfully used a terahertzlaser to induce permanent changes in the conformation of a polymer, giving it an increased pattern of crystallisation. Conformational changes are very important for macromolecular science because they can change the characteristics of a material and, in the case of proteins, can make it either possible or impossible for them to per...
