For the first time, polarized‐light‐emitting quantum‐rod diodes have been successfully produced, using thin layers of quantum rods oriented by a rubbing technique. Diode emission at 620 nm with a luminance efficiency of 0.65 Cd A –1 and an external quantum efficiency of 0.49 % is obtained (see Figure and inside cover).
