High-Performance solar-blind flexible Deep-UV photodetectors based on quantum dots synthesized by femtosecond-laser ablation

Abstract High-performance deep ultraviolet (DUV) photodetectors operating at ambient conditions with 3 N 2 ) without any material degradation due to water and oxygen molecule species, allowing photodetectors operate at ambient conditions. Carbon-doped ZnO QD-based photodetector is capable of detecting efficiently in the DUV spectral region, down to 224 nm, and exhibits high photo-responsivity and stability. As fast-response of DUV photodetector remains significant parameter for high-speed communication; we show fast-response QD-based DUV photodetector. Such surfactant-free synthesis by FLAL can lead to commercially available high-performance low-cost optoelectronic devices based on nanostructures for large scale applications.
