To overcome these limitations, we have developed ultra-flexible Ga₂O₃-based photodetectors with plasmonic Au-nanoparticles (Au-NPs) on a paper substrate. Incorporating Au-NPs enhances light absorption through localized surface plasmon resonance, extending the detection range from UV-C to NIR. The pristine device exhibits a responsivity of 20.96 mA/W at 266 nm, while the Au-NP-functionalized device achieves 38.86 mA/W, demonstrating a ∼185 % enhancement due to efficient hot carrier generation and improved charge transfer.
