Resumo

Zinc oxide (ZnO) is a material that, depending on its properties, can be found in applications ranging from the most simple (food additives) to the most sophisticated ones (UV lasers). Because of such versatility, it is natural to explore alternative forms of ZnO that, ultimately, can be used to develop new ZnO-related properties or devices. Stimulated by these facts, this work was concerned with the light emission characteristics of ZnO in the form of micrometer-sized flake-like structures (mu fk-ZnO). The samples were produced by thermal oxidation of a Zn film deposited by sputtering, and their main properties were investigated by morphological-structural-optical techniques. Along with a concise description involving the mu fk-ZnO formation and its luminescent characteristics, the work also suggests the suitability of mu fk-ZnO as a broad-band (white) light source.
