【 摘 要 】

An UV-Ozone reactorwas developed with an ignition tube extracted into HID mercury lamp used toirradiation on zinc oxide (ZnO) and fluorinated tin oxide (FTO) films for PLEDsdevices. Different exposures times were used. In contact angle measurementsrevealed better results for ZnO and FTO by 15 and 5 min, respectively. In DiffuseReflectance Infra-red Fourier Transformed (DRIFT) spectroscopy allowed the observationof water, hydrocarbon and carbon dioxide adsorbed on the untreated TCO surfaces.After the UV-Ozone treatment the contaminants were significantly reduced oreliminated and the PLEDs devices decreased threshold voltages in comparisonwith respectively untreated TCOs.
