Outline of Final Research Achievements

A light emitting device based on silicon (Si), which is a major semiconductor material for large scale integrated circuits (LSI), is expected for micro displays and optical interconnections. In this study, Si-based light-emitting devices, of which wavelength was visible and ultraviolet range, were fabricated and measured. The luminescent insulator layers were fabricated from the mixtures of organic liquid sources of rare earth elements, which were spin-coated on the Si substrate and annealed in air. The rare earth elements such as Tb, Eu, Gd, etc. and the combinations of Ca、Ba、Ta were examined. Electroluminescence (EL), whose wavelengths corresponded to radiative transitions of the rare earth ions, were observed. The device with Gd oxide layer showed ultraviolet EL of about 310 nm wavelength.
