Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2006.
Includes bibliographical references (p. 81-84).
This thesis demonstrates a new deposition method of colloidal quantum dots within a quantum dot organic light-emitting diode (QD-LED). A monolayer of quantum dots is microcontact printed as small as 20 ,Lm lines as well as millimeter scale planes, and the resulting devices show quantum efficiencies as high as 1.2% and color saturation superior to previous QD-LEDs'. Through a modification of the polydimethylsiloxane (PDMS) stamp with a parylene-C coating, quantum dots solvated in chloroform were successfully inked and stamped onto various substrates, including different molecular organic layers. The ability to control the placement and the pattern of the quantum dots independently from underlying organic layers provides a new level of performance in QD-LEDs, increasing the possibility of QD-LED displays.
