Kapljično tiskanje transparentnih oksidov

HUSSU, ŽIGA (author), Topič, Marko (mentor)

V osnovi je bilo za diplomsko delo mišljeno tiskanje OLED (organic light-emitting diode) s Fujifilmovim Dimatix DMP-2800 Series tiskalnikom, kar se je izkazalo za prekompleksno, zato je bila ideja poenostavljena na tiskanje le ene od plasti, ki sestavlja diodo z prevodnim transparentnim IZO (indij-cinkov oksid) in da določim njene optične in električne lastnosti. V začetnem delu naloge so opisani različni tiskalniki in postopki tiskanja, ki imajo sposobnost nanosa funkcionalnih plasti, kar je potrebno pri tiskani elektroniki. V raziskovalnem delu naloge pa so opisane priprave na tiskanje, uporaba Dimatix – DMP-2800 Series tiskalnika, tiskanja, sušenja in pečenja IZO črnila, ter opis optičnih meritev narejenih z Spektrofotometer Lambda 950 za celoten spekter vidne svetlobe in meritve, ki so grafično prikazane.

Abstract

The primary idea for my thesis was the printing of OLEDs (organic light-emitting diodes) using Fujifilm Dimatix-DMP-2800 printer. The process would be too complex and was simplified to print the base layer of an OLED with an conductive transparent IZO (indium-zinc oxide) ink and to measure its optical and electrical characteristics. In the first part of the thesis I compare the different types of printers that have the ability to print functional layers, which serve as the basis for printed electronics. The experimental part of the thesis consists of a description of the preparations needed before printing, the usage of the Diamatix-DMP-2800 Series printer, the printing procedure, how to dry and bake IZO ink, and the description of the process of measuring optical characteristics with the Lambda 950 spectrophotometer for the entire visible light spectrum, followed by graphically presented results.
