dc.description.abstract In the present paper, the optical characterization of a geopolymer synthesized at three different temperatures (40, 60 and 90 °C) is described. The results were correlated to the porosity fraction in order to obtain a photoluminescent geopolymer. A two-flux model was employed to relate the fraction of light absorbed, remitted and transmitted by a representative layer of geopolymer. Porosity was measured by nitrogen adsorption and correlated with the optical properties to determine the fraction of UV/Vis light transmitted through the samples. It was found that the geopolymer synthesize temperature and the incident wavelength greatly affect the fraction of light transmitted by the samples. The UV/Vis spectrum was divided into three zones according to the observed behavior. In the first zone, the difference in transmission fraction was significant; in the second zone, this difference decreased and practically vanished at the third one. Considering the highest transmission fraction at 90 °C, a photoluminescent geopolymer with the strongest emitting peak at 469 nm was synthesized. © 2010 Elsevier B.V. All rights reserved. es_ES
