UV and Visible range Electroluminescence from MOS Devices Fabricated by Spin-Coating of Gd/Dy Organic Compound Films on Silicon

Abstract

UV and visible range EL from MOS devices with spin-coated Gd silicate-related oxide having additive elements of Dy is presented. The devices emitted UV and visible wavelength range EL, which originated from the intrashell transitions in Gd 3+ and Dy 3+ , respectively. The surface silicate layer is analyzed by the XPS depth profiles and an EL mechanism is discussed.
