Zinc Oxide Based Light Emitting Diodes
76088S The currently-used transparent conducting oxide electrode for OLED construction is very expensive. It is desired not only to lower the electrode material cost, but also to lower its electrical resistivity and increase its optical transmissiveness. In order to improve the cost and efficiency of OLEDs for solid-state lighting, this project will develop an alternate transparent conducting oxide electrode. In Phase I, selectively-doped conducting oxides were deposited on polished glass substrates. The substrates were converted into fully functional OLEDs. In Phase II, these conducting oxides will be deposited on flexible substrates for fabrication of green colored exit signs. Commercial Applications and Other Benefits as described by the awardee: The alternative transparent conducting oxide electrode should provide for lower cost and higher performance exit signs that have high brightness. Other applications for the transparent conducting oxides are in flat panel displays, electrochromic mirrors and windows, and defrosting windows.
