Studies on Nanostructured ZnO as Sun-Screen Component

Author(s): A. U. Bajpeyee

The popularity of the sunscreens is significantly increased since ultraviolet (UV) radiations have foremost effects in the skin aging. The size of the materials especially nano-sized materials used in lotions also has major contribution. In this nano-particle era, it is desired to synthesis legitimate materials for the sunscreens. Among the category of organic and inorganic materials, inorganic materials provide the best spectrum protection against UV radiations as a physical Sun blocker dominant than chemical sunscreens. Thus, as one of the pass up elements among all is considered to be a zinc oxide and its synthesis. Furthermore efforts can be taken in this direction by synthesizing such inorganic material for skin protection, aging, filters and tumor preventers with the control of its particle size rather than crystallite size and hence has been studied with respect to X-ray diffraction (XRD) and Transmission Electron Microscopic (TEM) images followed by UV-VIS study to obtain 3.185 eV optical band gap.
