Morphology and photoluminescence properties of SrCO3 prepared by a simple solution method

SrCO 3 particles were prepared at 450–600   °C by a simple solution method. The phase structure, morphologies and photoluminescence (PL) properties of particles were investigated. All of the as-synthesized samples are orthorhombic SrCO 3 phase. SrCO 3 particles are composed of fibers aggregates and have layered morphologies. When excited by an appropriate wavelength, a broad emission band can be observed in the samples ranging from ultraviolet to red light region. The PL properties of samples were significantly affected by the fibers. SrCO 3 particles with fine and short fibers structure have excellent PL properties. In our experiment, SrCO 3 particles synthesized at 450   °C exhibit the strongest PL properties.
