Synthesis and characterization of hydroxyapatite nanobelts and nanoparticles

In the present paper, the nanobelts and sphere nanoparticles of hydroxyapatite (HA) had been synthesized using normal (oil in water) surfactant. The experimental results showed that the nanobelts consisted of uniform one-dimensional nanofibers with a width of 1.37 nm. The particle size of the sphere nanoparticles was about 55-60 nm. The presence of these resonance of phosphorus was in at least two types of phosphorus environments. The spectra of the nanobelts and sphere nanoparticles contained two typical bands of hexahedra Ca2+ at 200 and 210 nm. The Eg values for the HA of microcrystalline, sphere nanoparticles, and nanobelts samples were 1.60, 1.69 and 1.70 eV, respectively.
