Strontium carbonate (SrCO3) nanostructures with different morphology from bundles of nanorods to branchlet-like were synthesized by a simple and cost effective wet chemical method. Surface of nanoparticles capped by the adsorption of surface modifying agents is known for strongly influence the physicochemical properties. Therefore, in this contribution, the effect of well-established capping agent Triethylamine (cas 121-44-8) (TEA) on the morphology of SrCO3 has been investigated. The effect of TEA on morphology and the size of the particles have been evaluated by field emission scanning electron microscopy (FESEM) and X-ray diffraction (XRD) analyses. As increase in the concentration of TEA lead to the formation of branchlet-like morphology. The as prepared samples were extensively characterized by various spectroscopic techniques such as Fourier transform infrared spectroscopy (FTIR) and Raman. To gain further information on the electronic states of nanostructure, X-ray photoelectron spectroscopy (XPS) analysis was carried out, which showed that peaks shift in the electronic state of Sr at higher concentration of TEA. This study thus led to a better understanding of evaluation of organic matter on the morphology of SrCO3 nanostructure.
