| Abstract: | The present article presents first comparative study on three different dry solgel methods of producing new alumina‐based dark violet, light pink ceramic nanopigments as well as ruby‐red ceramic nanopigment — an alternative to the Purple of Cassius. Gold nanoparticles are built directly on a carrier of an aluminum oxide nanopowder, which finally yields Al2O3/Au nanopowders possessing colors ranging from light pink to light violet as well as ruby‐red. |
