Abstract

Upright Zn

GeO

/ZnO nanorod arrays were prepared on silicon wafer with two kinds of seed layers (metal Au and ZnO seed) by the chemical vapor deposition(CVD) method. Scanning electron microscopy (SEM)

X-ray diffractometer (XRD) and photoluminescence (PL) measurements were used to characterize the samples and reaseach its luminescence properties. The results show that the radius of Zn

GeO

/ZnO nanorod is 350-400 nm and the length is 10-11 m. The photoluminescence spectrum (PL) of Zn

GeO

nanorods exhibites three fluorescence emission peaks centered at 415

445

488 nm. Moreover

a detailed description of the probable growth mechanism of the upright Zn

GeO

/ZnO nanorod arrays was discussed. Its vertical orientation is desirable for use in optoelectronic field.
