Abstract
Quantum dot/conducting polymer hybrid films are used to prepare light‐emitting diodes (LEDs). The hybrid films (CdSe@ZnS quantum dots excellently dispersed in a conducting polymer matrix, see figure) are readily prepared by various solution‐based processes and are also easily micropatterned. The LEDs exhibit a turn‐on voltage of 4 V, an external quantum efficiency greater than 1.5%, and almost pure‐green quantum‐dot electroluminescence.Keywords
