Abstract

In this paper

Cd-doped ZnO(Cd/ZnO) composite was successfully prepared by hydrothermal method.The effect of different doping concentrations on the structure of ZnO was studied.It was found that the introduction of Cd would increase the size of ZnO particles and effectively reduce the band gap of ZnO.The experimental results show that the Cd/ZnO-1 sensor exhibits good humidity-sensing performance when the molar ratio of Cd2+ to Zn2+is 0.01.In the range of 11～95% relative humidity

the response of the Cd/ZnO-1 humidity sensor is 1120

the maximum hysteresis error is 3%

the response and recovery time are 36 s and 5 s

and it has good repeatability.Therefore

the Cd/ZnO-1 humidity sensor has a potential to develop a high-performance humidity sensor

and it also provides a new idea for the preparation of new humidity sensors.
