We venture to design and fabricate thermosensitive flexible ultraviolet (UV) detector, and the response time of the MCN-graphene composite is decreased 7500 times, while the quantum efficiency of MCN is increased from 1 to 13.5%. Meanwhile, the noise level is 104 times lower than that of common GaN and ZnS UV sensors. Additionally, the shortcoming of low light absorption of graphene for use as a sensor is overcome, so that the light responsiveness reaches 0.5 WA. For the first time, a thermal sensor functions at the same level of performance as an flexible optoelectronic sensor.
