Various nanostructures are directly written by electron‐beam‐induced deposition using dimethyl‐gold(III)‐acetylacetonate as the precursor gas. After purification, their potential applications include plasmonic devices and metamaterials. Carbon contamination of the as‐written structures can be completely removed by low‐temperature ozone treatment, leaving polycrystalline pure gold structures (see figure). This treatment reduces the size of the nanostructures but does not substantially alter their functional shape.
