Inkjet Printing of an Electron Injection Layer: New Role of Cesium Carbonate Interlayer in Polymer OLEDs.

Among solution-processable techniques, inkjet printing is a potential method for manufacturing low-cost and high-resolution polymer organic light-emitting diodes (PLEDs) for displays/solid-state lighting applications. Herein, we demonstrate use of the inkjet printed cesium carbonate (CsCO) film as an electron injection interlayer. We have elaborated the CsCO ink using an alcohol-based solvent for the industrial-grade printhead.

Inkjet Printing of Super Yellow: Ink Formulation, Film Optimization, OLEDs Fabrication, and Transient Electroluminescence.

Inkjet printing technique allows manufacturing low cost organic light emitting diodes (OLEDs) in ambient conditions. The above approach enables upscaling of the OLEDs fabrication process which, as a result, would become faster than conventionally used vacuum based processing techniques. In this work, we use the inkjet printing technique to investigate the formation of thin active layers of well-known light emitting polymer material: Super Yellow (poly(para-phenylene vinylene) copolymer).

Lyot depolarizer in terms of the theory of coherence--description for light of any spectrum.

A coherence-based description of the Lyot depolarizer illuminated by polychromatic light of any spectral density distribution is proposed as a generalization of the formulas provided for symmetrical spectra by Burns [J. Lightwave Technol. 1, 475 (1983)] and Mochizuki [Appl.
