Abstract

The p-i-n junction in a polymer light-emitting electrochemical cell (LEC) is stabilized by cooling the device below the glass transition temperature of the ion-transport polymer. LECs with frozen p-i-n junctions exhibit typical light emitting diode (LED) behavior including diode rectification, unipolar light emission (same polarity as that used for generating the junction), and fast response. The freezeout of ion motion allows polymer LECs to be driven at bias voltages well beyond the electrochemical stability window, and thereby extends the potential applications of polymer LECs to high pixel density, column-row addressable displays. {copyright} {ital 1997 American Institute of Physics.}

Steady state model for polymer light-emitting electrochemical cells

Journal Article Smith, D L - Journal of Applied Physics

A model is presented for the steady state operation of polymer light-emitting electrochemical cells (LECs). An LEC consists of a luminescent and ionically conducting polymer, with an ionic salt added to provide ions necessary for p-type and n-type doping, sandwiched between two electrodes. Upon applying a sufficiently large voltage bias, the ions are spatially separated forming an electrical junction. Electrons injected from the n-type side of the junction recombine with holes injected from the p-type side of the junction emitting light. We first describe the LEC at zero bias in which electric fields may occur in charge double layers nearmore »« less

Polymer light-emitting devices: Light-emitting diodes and light-emitting electrochemical cells

Conference Heeger, A J ; Cao, Y ; Pei, Q ; ...

We will summarize recent progress using two different device configurations: tunneling injection light-emitting diodes (LEDs) and light-emitting electrochemical cells (LECs). In the LEC, a p-n junction diode is created in-situ through simultaneous p-type and n-type electrochemical doping on opposite sides, respectively, of a film of conjugated polymer which contains added electrolyte to provide the necessary counterions for doping. Blue, green and orange emitting LECs have been fabricated. The LEC has been used to directly measure the charge injection energy gap in semiconducting polymers. Simultaneous measurements of the onset of electrochemical doping, electrical injection, and electroluminescence from light-emitting electrochemical cells eliminatesmore »« less
The dynamic behavior of thin-film ionic transition metal complex-based light-emitting electrochemical cells

Journal Article Meier, Sebastian B., E-mail: sebastian.meier@belectric.com, E-mail: wiebke.sarfert@siemens.com ; Siemens AG, Corporate Technology, CT RTC MAT IEC-DE, 91058 Erlangen ; Hartmann, David ; ... - Journal of Applied Physics

Light-emitting electrochemical cells (LECs) have received increasing attention during recent years due to their simple architecture, based on solely air-stabile materials, and ease of manufacture in ambient atmosphere, using solution-based technologies. The LEC's active layer offers semiconducting, luminescent as well as ionic functionality resulting in device physical processes fundamentally different as compared with organic light-emitting diodes. During operation, electrical double layers (EDLs) form at the electrode interfaces as a consequence of ion accumulation and electrochemical doping sets in leading to the in situ development of a light-emitting p-i-n junction. In this paper, we comment on the use of impedance spectroscopymore »« less

Direct observation of junction formation in polymer light-emitting electrochemical cells

Journal Article Gao, J ; Heeger, A J ; Campbell, I H ; ... - Physical Review, B: Condensed Matter

Electroabsorption (EA) measurements are used to determine the electric fields in polymer light-emitting electrochemical cells (LEC{close_quote}s). The EA signals are measured as a function of the dc bias and are found to increase abruptly above a threshold voltage. The EA measurements are compared with the capacitance-voltage and current-voltage characteristics. Calculations using a model based on electrochemical junction formation are in agreement with all of the experimental observations. These results show unambiguously that the picture of electrochemical junction formation in LEC{close_quote}s is correct. {copyright} {ital 1999} {ital The American Physical Society}

Light-emitting electrochemical cells from a blend of p- and n-type luminescent conjugated polymers

Journal Article Yang, Y ; Pei, Q - Applied Physics Letters

We demonstrate polymer light-emitting electrochemical cells (LECs) made of a blend of p- and n-type luminescent conjugated polymers. These two polymers, poly[9-(3,6,9-trioxadecyl)- carbazole-3,6-diyl] (TOD{endash}PC, a p-type polymer) and poly[2,3-di(p-tolyl){endash}quinoxaline-5,8-diyl] (DT{endash}PQX, a n-type polymer), are blue and blue{endash}green emission polymers, respectively, both with high photoluminescent quantum efficiency. However, the photoluminescence of the polymer blend is completely quenched, due to the charge transfer between the two polymers. A new and faint orange{endash}yellow photoluminescence emission, which has photonic energy consistent with the energy difference of the {pi} band of TOD{endash}PC and the {pi}{sup {asterisk}} and of DT{endash}PQX, has been observed. LECs fabricated frommore »« less
