Resumen

GUAJARDO-PACHECO, J.M.; ORTEGA-ZARZOSA, G.  y  MARTINEZ, J R. Fluorescents effects of silica xerogel induced by incorporation of chard leaves extracts and ZnO nanoparticles. Superf. vacío [online]. 2008, vol.21, n.1, pp.16-19. ISSN 1665-3521.

This work studies the effect of incorporating fluorescent organic extracts and oxide zinc nanoparticles in silica xerogel composites prepared by the sol-gel method, under different condition of preparation, which confer different optical and structural characteristics to product. The samples at room temperature and heat-treating at annealing temperature were studied using infrared spectroscopy, fluorescence, X-ray diffraction and differential temperature analysis.

Palabras llave : Sol gel; Fluorescence; Chlorophyll; Zinc oxide nanoparticles.
