The XRD curves indicate the sample has polycrystalline hexagonal wurtzite structure. The XRD data of the sample prepared at 250C and 300C has a bigger angle shift about 0.05and 0.3respectively. That indicate the structure of the sample has some changes. The EDS indicate the sample contains Zn  O and C. So the XRD shift may attribute to the C. The XPS indicate the C doped in the crystal lattice of ZnO of the sample prepared at 300C  and the sample prepared at 250C may be only a few of C doped in the crystal lattice of ZnO. The PL of the sample prepared at 300C only has a weak ultraviolet emission  which indicates C modified the nanocrystalline ZnO surface as a non-radiative recombination center. In this process C could non-radiatively recombine the carries on the nanocrystallin ZnO surface. The sample prepared at 250C has a strong visible emission at about 530 nm. This emission band could be attributed to oxygen vacancy because C schlepped some oxygen on the nanocrystalline ZnO surface.   Application of the attribute recognition method for the evaluation of spatial data quality - art. no. 642014 会议论文  OAI收割 Geoinformatics 2006: Geospatial Information Science, Bellingham Sun, Qinghui; Chi, Tianhe; Zhong, Dawei 收藏  |  浏览/下载：25/0  |  提交时间：2014/12/07 attribute mathematics  spatial data quality  evaluation of spatial data  quality  attribute recognition model  quality evaluation model  geographical information system   Project research of GIS data based on AutoCAD 期刊论文  OAI收割 TRANSACTIONS OF NONFERROUS METALS SOCIETY OF CHINA, 2005, 卷号: 15, 页码: 236-238 作者:  Yao, X   |  收藏  |  浏览/下载：19/0  |  提交时间：2018/09/26 Autocad  Attribute Data  Data Transfer  Objectarx  Xdata
