ABSTRACT
Nanotechnology met a lot of applications in several advanced fields. Recently it has gained a lot of research efforts. Zinc oxide nano materials are promising candidates for nano electronic and photonics. ZnO is unique because it exhibits dual semiconducting and piezoelectric properties and can be used in gas sensing and in biomedical science because it is bio-safe. ZnO is a material that has diverse structures, whose configurations are much richer than any known nanomaterials including carbon nanotubes. Zinc oxide powders were synthesized via, sol-gel technique and Pechini method using zinc acetate dihydrate as source of zinc oxide. The obtained zinc oxide powders were dried at 100°C and calcined at different temperatures (500, 700 and 900°C). The samples were characterized by FTIR and their morphology were examined by SEM. The advantages and disadvantages of the two techniques and their expected applications were recorded.
