Abstract

Zinc Oxide (ZnO) is a metal oxide semiconductor that used for organic light emitting diode (OLEDs) applications. The ZnO nanotetrapods nanotetrapod of various time depositions has been synthesized using thermal chemical vapor deposition (thermal-CVD) method. In this study, the synthesizations were deposit at 30 minutes and 50 minutes to investigate the time deposition effect of ZnO nanotetrapods. The optical properties were obtained using photoluminescence (PL). The PL spectra show that the sample at 30 minutes is the highest intensity for ultraviolet (UV) emission due to crystallization of ZnO nanotetrapods. X-Ray Diffraction was deposited using Broker AXS D8 Advance with Cu Kα radiation. It is show the highest peak can observe for sample 30 minutes. From FESEM images, it was found that the length of ZnO nanotetrapods increased with increased of time deposition.
