<p>The data package is the research data of our research project on <strong>Graphene hybrid photosensor. </strong>The data package includes the electrical tests result which are the raw data of our research. Based on these data,  we successfully fabricated spectral-selective graphene photosensor with photoresponsivity as high as 8.8×104 A/W thanks to the ultra high mobility of graphene and light absorption efficiency of organic dyes. Spectral-selective photoresponse enables graphene photosensors decorated with different organic dyes exhibit distinct absorption spectrum which is essential for a full colour image sensor. The photocurrent generated in the photodetector is in proportional to the incident optical power and reaches a saturation plateau when the light intensity is over 0.1 μW.</p> <p>To develop an integrated, spectra-selective, full colour gamut photosensor for colour imaging, we did tentative test to scale up photosensor array with 1 μm thick Parylene thin film, the spectral response test demonstrate inducing Parylene C would not significantly affect the photoresponsivity and absorption spectrum while providing a physically and chemically stable encapsulation.</p>
