A Bright Future For InGaN Photonic Crystal Light Emitters
Via a bottom-up approach this research shows the production of scalable, stable InGaN nanowire photonic crystals for high efficient LEDs.
Magnetic-Field-Modulated Tuning of Light-Emitting Properties
Researchers from Hong Kong Polytechnic University and the Hong Kong Polytechnic University Shenzhen Research Institute achieve remote and temporal tuning of luminescence intensity and wavelength in green- and blue-emissive piezophosphors by modulating the magnetic field. This novel method is promising for applications in magnetic optical sensing, piezophotonics, energy harvesting, nondestructive environmental surveillance, novel light sources, and displays.
“Painting” with Light for Electroluminescent Displays
A novel, electroluminescent device concept that can emit light in response to the accumulation and distribution of materials on the device surface is developed.
Holographic Optical Tweezers Applied to Living Zebrafish Embryos
A complementary technique, based on the Holographic Optical Tweezers (HOT) technique, which enables several locations within the same sample to be probed simultaneously, is developed.
Stabilizing Optical Coherence Tomography
An American team of scientists develop a novel phase stabilization technique with significant improvement in the phase stability of a micro-electromechanical (MEMS) vertical cavity surface-emitting laser (VCSEL) based swept-source optical coherence tomography (SS-OCT) system.
Periodic Silver Nanopore and Nanoparticle Arrays with Controlled Shape and Size
A unique and versatile approach to creating ordered silver nanostructures is presented that allows for feature shape alteration in a simple and inexpensive manner.
Plasma Makes POSS Nanomaterials More Effective and Environment Friendly
A new study introduces an innovative and cost-effective technique for the plasma functionalization of POSS micro-powders without damaging the nanocage structure they are based on.
Live–Cell Imaging via a Clickable Probe With an Exceptionally Long Lifetime Shift
–Cells are highly complex and organized entities which are composed of various biological events. Real-time live-cell imaging is important for understanding these physiological processes. However, many existing fluorescent probes are unsuitable for these purposes due...
