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.
