Abstract

Polarized-light-emitting quantum-rod diodes have been successfully produced using thin layers of quantum rods oriented by a rubbing technique, as shown on the inside cover. Hikmet and co-workers report on p. 1436 that diode emission at 620 nm with a luminance efficiency of 0.65 cd A<sup>-1</sup> and an external quantum efficiency of 0.49 % is obtained. Light emitted polarized parallel to the long axis of the rods is 1.5 times more intense than that polarized perpendicular to the rods.
