The photoresponse properties of solution processed graphene oxide (GO) ranged from ultraviolet-visible-near infrared regime are studied. Photoelectrochemical results indicate that the as-prepared GO devices have excellent sensitivity, high-speed and superior reproducibility as a visible and near infrared photodetector. Especially, the responsivity and external quantum efficiency are found to be about 95.8Â mA/W and 26.2%, respectively, for incident wavelength of 455Â nm at 0.8Â V bias voltage. Resulting from the degradation of GO under UV irradiation, the GO devices exhibit unstable photoresponse performance, as well as high UV photosensitivity.
