A novel full near infrared laser processed gold nanoparticles (Au NPs)/indium-zinc-oxide (IZO) photodetector is successfully demonstrated. The coupling of dewetted Au NPs works as nanoheaters, which lets IZO can be cured at low environmental temperature. Additionally, with the improved absorption given by Au NPs from localized surface plasmon resonance effect, the photodetector is able to perform wide range detection from 410-780 nm with good operating stability and reliability.
