UV photoresponsivity of sol-gel derived Al-doped ZnO nanorod array

UV photoresponsivity of sol-gel derived Al-doped ZnO nanorod array

Ultraviolet (UV) photoconductive sensor were fabricated based on aluminum (Al) doped zinc oxide (ZnO) nanorod arrays at different doping concentrations varied from 0 at.% (undoped) to 2 at.% which were deposited on glass substrates using immersion method. The average diameter of nanorods decreased w...

Ultraviolet (UV) photoconductive sensor were fabricated based on aluminum (Al) doped zinc oxide (ZnO) nanorod arrays at different doping concentrations varied from 0 at.% (undoped) to 2 at.% which were deposited on glass substrates using immersion method. The average diameter of nanorods decreased with increased of Al doping concentration. The transmittance of all samples is above 70% in the visible regions. The electrical properties were improved by dopant concentrations as shown by I-V measurement results. UV responsivity and sensitivity of 0.8 at.% Al doping concentration is the highest compared to other samples with value of 8.81 A/W and 51.67, respectively. © 2019 Author(s).
