Abstract

Syntesis of ZnO nano particles using co-precipitation methode with variation of cu-doped consentrate has been done. This research devided by two part, the first part is syntesis process, and the second part is characterization process. The first step of synthesis process is by measuring Zn assetate and CuS mass to get variation of Cu –Doped consentration which is 0%, 2%, 4%, 6%, and 8%, then dissolved it with 150 ml HCl 0.5 M. The next step is by droping on solution slowly until pH 10, then the solution stired on a hotplate for 3 hours with 60⁰ C temprature. Next, the synthesis proceed is done after following this procees which is preticipation, purification, and drying with 150⁰ C. Characterization proses has been done by using SEM-EDX and XRD. Ressult by using XRD ZnO phase found in 0%, 4%, 6%, and 8% Cu-doped. The smallest average of diameter crystallin acquaired from a sampel without Cu-doped which is 29 nm, and the largest is acquaired from a sampel with 8% Cu-doped which is 37 nm. SEM-EDX result shown particles morfology and the persentage of mass and atom. As it result can be concluded The persentage of mass and atom Cu greater along the consentration

Abstract

Nanomaterials have a variety of uniqueness and attractiveness, it is considered necessary to carry out literature study, beside the laboratory investigation, among others, on the nanoparticle structure and energy gap of ZnO nanoparticles doped with aluminum (Al) resulting from synthesis using various methods. In this study, the structure of the nanoparticles was divided into three types, namely crystal structure, crystallite size, and morphology. The crystal structure of the Al doped ZnO nanoparticles is hexagonal wurtzite. It is found, that, a decrease in crystallite size occurs as the doping of Al into ZnO increases to its solubility limit. A similar pattern also occurs in particle size. The high concentration of Al doping results in agglomeration. The morphology of Al doped ZnO nanoparticles in some references of this study are rod, spherical, and irregular spheres. The energy gap value of Al doped ZnO nanoparticles increases with the increasing concentration of Al doping in ZnO. So, it can be said, that Al as a doping material has an influence on the structure and optical properties of ZnO nanoparticles.
