Optical materials news, October 2019

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.
