Optical materials news

German Research Foundation honours Dr. Baptiste Gault with Gottfried Wilhelm Leibniz Award

Scientists have found an organic compound that can harvest the 'hot electrons' produced when high-energy photons hit a perovskite semiconductor.

Researchers have developed new organic-inorganic hybrid perovskite materials that don't contain lead and have a much improved stability.

Perovskite materials for use in next generation solar cells and flexible LEDs can be more efficient when their chemical compositions are less ordered.

By applying an intermittent electrical field, researchers have managed to get blue-phase liquid crystals to adopt novel structures with novel properties.

By replacing some of the lead in perovskites with indium, scientists have quashed the defects in perovskite solar cells and enhanced their stability.

Exposing the cathode in a lithium-ion battery to a beam of concentrated light can lower the charging time by a remarkable factor of two or more.

By wetting porous polymer coatings with alcohol, researchers have come up with an inexpensive and scalable way to control light and heat in buildings.

A subtle interaction between single atomic defects in the 2D material tungsten diselenide and mechanical strain causes it to emit quantum light.

Researchers have developed silk materials that can wrinkle into highly detailed patterns, which can be erased by flooding the silk surface with vapor.

novel electroluminescent device uses flexible, electrically conductive Ag-coated nylon fibers embedded in a PDMS + ZnS composite as electrodes

Engineers have harnessed machine learning to design dielectric metamaterials that absorb and emit specific frequencies of terahertz radiation.

By combining different materials, scientists have created highly configurable, nanoscale thermal light emitters for producing light from heat.

Smart skin that responds to heat and sunlight

Researchers have found that doping indium oxide with molybdenum rather than tin doubles the conductivity of this transparent conductor.

Coating chlorine-etched aluminum foil with carbon nanotubes created a material that is 10 times blacker than anything previously reported.

Crystallographic dislocations can impact the ability of halide perovskites to hold energy derived from light in the form of excited electrons.
