Raman spectroscopy in aluminum-doped zinc oxide nanorods

Aluminum-doped zinc oxide nanorods are deposited on glass by solution chemical for the first time. The as-grown samples are characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), UV-Vis spectroscopy and Raman spectroscopy. We observe that Raman spectroscopy of aluminum-doped zinc oxide nanorods is different from un-doped zinc oxide nanorods. The intensity of Raman peak at 437 cm
⁻¹
is decreased for aluminum-doped zinc oxide nanorods sample while peak at 750 cm
⁻¹
appears. X-ray diffraction (XRD) shows aluminum-doped zinc oxide nanorods grown in the (002) orientation. UV-Vis spectroscopy shows no difference in the aluminum-doped zinc oxide nanorods than undoped zinc oxide nanorods.
