| Abstract: | Transparent pale yellow ZnO crystals with different hexagonal morphology,such as hexagonal caps and hexagonal lamellae,have been successfully synthesized in molten hydrous NaOH-LiOH.The phase structure of the as-grown crystals was investigated by means of X-ray powder diffraction.Detailed surface morphology of the crystals was studied using optical microscopy and scanning electron microscopy.Elemental analysis of the synthesized crystals was performed using energy dispersive X-ray spectrum.The photoluminescence spectrum was employed to characterize the obtained crystals.Some ultraviolet,blue,green and red emission peaks were observed in the photoluminescence spectrum. |
