With CuC12 as copper source and Na2CO3 as precipitant,CuO microspheres of 1-3 μm diameter were successfully synthesized via hydrothermal method at 180 ℃ for 24 h. The samples were characterized using X-ray diffraction,thermal field emission scanning electron microscope and ultraviolet-visible absorp- tion spectroscopy, respectively. The results indicate that with the increase of Na2 CO3 dosage, the morpholo- gy of CuO microspheres changes from needle-like shape to granular shape. And then needle-like CuO spon- taneously aggregates to form CuO microspheres. CuO microspheres have good optical absorption proper-ties.
