The Singapore University of Technology and Design (SUTD) and its research collaborators have successfully demonstrated the four-dimensional (4D) printing of shape memory polymers in submicron dimensions which are comparable to the wavelength of visible light. This novel development has allowed researchers to now explore new applications in the field of nanophotonics.
Organic luminescent materials have been highlighted as an exciting research topic owing to their prominent potentials in light-emitting diodes, fluorescent sensors, optoelectronic devices, in vivo imaging, anti-counterfeiting, data storage, and information encryption.
A recent study has measured the internal quantum efficiency (IQE) of Zinc-Oxide (ZnO) crystals in both the light-emitting process and non-light-emitting process.
Nonlinear photonic crystals (NPCs) are transparent materials that have a spatially uniform linear susceptibility, yet a periodically modulated quadratic nonlinear susceptibility.
The images reveal that vibrational strong coupling can be achieved, which is a phenomenon that recently attracts wide attention for its potential use to control fundamental physical and chemical material properties.
Using modern nanotechnology, it is possible nowadays to produce structures which have a feature sizes of just a few nanometres. This world of the most minute particles - also known as quantum systems - makes possible a wide range of technological applications, in fields which include magnetic field sensing, information processing, secure communication or ultra-precise time keeping.
Scanning lasers -- from barcode scanners at the supermarket to cameras on newer smartphones -- are an indispensable part of our daily lives, relying on lasers and detectors for pinpoint precision.
The right indoor lighting can help set the mood, from a soft romantic glow to bright, stimulating colors. But some materials used for lighting, such as plastics, are not eco-friendly. Now, researchers reporting in ACS Nano have developed a bio-based, luminescent, water-resistant wood film that could someday be used as cover panels for lamps, displays and laser devices.
Photodetectors have always paly the important role in the national economy and national defense field. The advanced photodetectors demand for the higher performance in response rate, broad spectrum, detectivity and other special functions like polarization detection and two-color detection.
Discovering and synthesizing symmetry-protected topological band degeneracies, including nodal points and nodal lines, is a rapidly growing frontier in the field of topological materials.
