Halide nanocrystal array emitting light

A rendering of a halide nanocrystal array emitting light. Researchers developed a technique to "grow" halide perovskite nanocrystals -- delicate materials with superior optoelectronic properties -- with precise control over the location and size of each individual crystal. The method allows the researchers to integrate the crystals into nanoscale light-emitting diodes, or nanoLEDs.
