摘　　要：We present here the first observation of cathodoluminescence (CL) images of Met.(Cu, Ag)-TCNQ anion radical salts organic thin films which were prepared in sat urated TCNQ/CH3CN liquid-phase by self-growth. The erperiments were carried out by means of Hitachi S-450 type scanning electron microscopy(SEM). Comparsion of CL images with secondary electron(SE) images of the same point on the organic thin film indicates that the shape of Met.(Cu, Ag)-TCNQ in CL images corresponds very well to that in the SE images. The results observed also shows that the CL intensity of CuTCNQ is stronger than that of AgTCNQ under the same experimental conditions. Based on the above results, a brief discussion about the preliminary mechanism of CL from Met.(Cu,Ag)-TCNQ has been given.We present here the first observation of cathodoluminescence (CL) images of Met.(Cu, Ag)-TCNQ anion radical salts organic thin films which were prepared in sat urated TCNQ/CH3CN liquid-phase by self-growth.
