| Summary: | 碩士 === 國立中興大學 === 光電工程研究所 === 104 === The purpose of this research is to fabricate a nano-scale thin film, titanium oxide deposited on Organic Light-Emitting Diodes as the out-coupling scattering structure by liquid phase deposition with the mixture of ammonium hexafluoro-titanate and boric acid. This high refractive index material would let the generated light emit efficiently to air and improve the light extraction efficiency of OLED. In this research, we controlled the particle size and film thickness of titanium oxide by changing the deposition time, then, the Field Emission Scanning Electron Microscope ( FE-SEM ) was used to observe the surface morphology of titanium oxide films. In the end, the UV-Visible Spectroscopy was used to analyze the transmittance of titanium oxide films. In green OLED, the optimal deposition time of nano-scale films, titanium oxide is 25 minutes, as the spectrum and lumen both gain 3.1 times.
