Episode 3: Copper-iodide hybrid material enables deep blue LEDs
In this podcast episode, MRS Bulletin’s Sophia Chen interviews Jing Li at Rutgers University and Kun Zhu at the Max Planck Institute of Microstructure Physics about the material and a solution-based manufacturing process they introduced to produce deep blue light-emitting diodes (LEDs). The LEDs emit light at 460 nm. The LED consists of several layers, beginning with an indium tin oxide (ITO) substrate that serves as an electrode. Above the ITO is a single molecular layer of the polymer, polymethyl methacrylate. An 85-nm layer of the emissive hybrid copper iodide material goes on top of the…
