Selective-controlled synthesis of one-dimensional strontium phosphates

Anorthic SrHPO4 nanobelts and hexagonal Sr10O(PO4)6 nanorods were obtained by a simple hydrothermal method without adding any surfactant as template. The as-synthesized products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM). TEM and HRTEM observations of the products revealed that the as-prepared SrHPO4 nanobelts and Sr10O(PO4)6 hexagonal nanorods are single crystals with their preferential growth direction along the normal of (1 0 0) and (0 0 1) planes, respectively.
