ZnO Gas -Sensitive Films Prepared Through Sol -Gel Process
Pan Suying Mei Sen(Wuhan Institute of Technology)
ZnO gas - sensitive films of fine grains which are uniformly distributed are prepared from Zn(CH3COO)2 through Sol-Gel process. Intrinsic fabric parameters were determined. By analysing the results of XRD and TEM, the films are thought as ZnO polycrystalline materials and the samples' gas-sensitivity are tested at different atmosphere by the high -resistance -meter.
