Abstract
Al doped ZnO(AZO) nanocrystals were prepared by a hydrothermal treatment with cetyltrimethyl ammonium-bromide (CTAB). It was found from TEM observation that the morphology of ZnO and AZO was changed to rods and spheres, respectively, in comparison with that without CTAB. AZO single phase was synthesized until Al content x=3 but ZnAl2O4 was precipitated over x=5. The lattice constants were linearly decreased up to x=5. A simple model calculation revealed that Al amount into ZnO was 1~1.5%.
