Iridescent photonic cellulose, which mimics the structural color of insects, with optical applications

A study developed at the ICMAB-CSIC and published in Nature Photonics describes the technique to provide structural coloration on a cellulose derivative through its nanostructuration. The colors obtained do not depend on pigments but on nanostructures that interact differently with the incident light. Applications include ecofriendly production of color in packaging systems or decorative paper, anti-counterfeiting technology, or biocompatible, biodegradable, washable and edible and low cost detectors, sensors or labels.

Organic and miniaturized photodetectors that absorb light beyond the visible range

They detect light below its absorption band and with a high efficiency. The presented devices demonstrate a wide spectroscopic photodetection and compactness of the device, making them much more portable and suitable for integrated electronics applications. The study was carried out by ICMAB researchers in collaboration with researchers from Dresden (Germany) and from Beijing (China).

Novel photonic materials made up on self-assembly particles for sensing applications

Spanish researchers from the Catalan Institute of Nanoscience and Nanotechnology (ICN2) and the Institute of Materials Science of Madrid (ICMM-CSIC) have formed highly-porous metal-organic framework particles that spontaneously assemble into well-ordered 3D superstructures that present photonic crystal properties. Their discoveries are expected to find applications in the design of novel photonic materials for sensing applications, among others.

Superabsorbers nanomaterials that trap sunlight

ICMAB researchers have designed ultrathin materials that maximize the absorption of light in a large range of the solar spectrum. The followed strategy is low cost and fully scalable. The obtained superabsorbers materials have many potential applications, especially in the field of photovoltaic energy and photodetection.
