“…It is also used in the production of paints, pigments, and fireworks [1,2]. Furthermore, because SrCO 3 exists in a single crystalline phase, it has been widely used as a model system for investigating the formation of biominerals [3,4]. Recently, nanocrystalline SrCO 3 (nano-SrCO 3 ) has attracted the attention of researchers because of its unique physical and chemical properties, which make it suitable for use in optical applications [5].…”
