We demonstrated the fabrication of Al-doped ZnO (AZO) nanosheets on a glass substrate using the aqueous solution method. AZO nanosheets for a metal–semiconductor–metal ultraviolet (UV) photodetector (PD) were prepared. The average length and diameter of the AZO nanosheets were 1.44 μm and approximately 25 nm, respectively. The EDX spectrum of the Al-doped sample indicates that it contains approximately 0.64% at% Al. Our results show the high sensitivity of the UV PD, which reached 5.98 × 105. The measured transient response time and recovery time were 0.7 and 2.5 s, respectively.
