Fabrication of Multilayer Polymer Light-Emitting Diodes with a Spin Coated Hole Transport Layer and Stamp Transfer Printed Emitting Layer

Abstract

High efficiency multilayer polymer light emitting diodes (PLEDs) were developed using a stamp transfer printing process. Light emitting polymers were stacked on the spin-coated polymeric hole transport layer by using a stamp transfer printing method. The light-emitting efficiency of PLEDs was improved by more than 60% by stacking the light emitting polymers on the hole transport polymers using the transfer printing process.
