| description | A simple and reliable ultraviolet sensing method with high sensitivity is proposed. ZnO and ZnO composite graphene are successfully prepared by the hydrothermal method. The optical fiber sensor is fabricated by coating the single-mode-taper multimode-single-mode (STMS) with different shapes of ZnO. The effects of the sensitivity of ultraviolet sensors are further investigated. The results show that the sensor with ZnO nanosheets exhibits a higher sensitivity of 357.85 pm/nW·cm<sup>−2</sup> for ultraviolet sensing ranging from 0 to 4 nW/cm<sup>2</sup>. The ultraviolet characteristic of STMS coated flake ZnO composite graphene has been demonstrated with a sensitivity of 427.76 pm/nW·cm<sup>−2</sup>. The combination of sensitive materials and optical fiber sensing technology provides a novel and convenient platform for ultraviolet detection technology. |
