ABSTRAK

Nanozarah zink oksida telah disintesis menggunakan afrons gas koloid sebagai acuan. Zink sulfat (ZnSO4.7H2O) dan gas ammonia digunakan sebagi bahan tindak balas. Masa pengeraman yang dikaji adalah 2 jam dan 18 jam. Daripada analisis mikroskop elektron imbasan, morfologi nanohelaian dapat diperhatikan dengan ketebalan helaian 125 nm hingga 200 nm. Daripada analisis spektroskopi ultra lembayung-boleh nampak, saiz purata yang dianggarkan bagi sampel nanozarah zink oksida yang disintesis dengan masa pengeraman 2 jam adalah 2.03 nm dan 2.1 nm untuk sampel yang dieramkan selama 18 jam.

Kata kunci: Afrons gas koloid; kesan masa pengeraman; nano ZnO; semikonduktor

ABSTRACT

Zinc oxide nanoparticles has been synthesized using colloidal gas aphrons as template. Zinc sulfate (ZnSO4.7H2O) and ammonia gas used as reactants. The incubation periods that have been studied are 2 h and 18 h. From the scanning electron microscope analysis, nanosheet morphology can be observed with thickness of 125 nm to 200 nm. From the UV-Vis spectroscopy analysis, the estimated average size for zinc oxide nanoparticles with 2 h incubation time is 2:03 nm and 2.1 nm for 18 h of incubation time.

Keywords: Colloidal gas aphrons; incubation effect; nano ZnO; semiconductor
