  • The objective of this project was to synthesis and to comparative characterization of nanocrystalline opals. Synthesis technique called Stöber allows obtaining nano and micro particles monodisperse. Natural opal of origin Mexican was utilized as reference. The results obtained indicated crystalline phases in the opal, and the presence of water is shown through x-ray diffraction and the FTIR and Raman spectra, respectively. Scanning electron microscopy illustrated spherical nanoparticle of silicon. We conclude that the synthetic opal presents a mimetic character.
