The coatings were consolidated at low temperature (range 60-180 A degrees C) preserving optical activity of quinine molecule. We designed a device to test the guiding properties of the coatings. We confirmed with this device that light injected in pure silica coatings is guided over distances of meters while quinine presence induces isotropic photoluminescence. With the combined use of both type of coatings, it is possible to design light guiding devices and illuminate regions in glass elements without electronic circuits.engjournal articlehttp://dx.doi.org/10.1007/s10971-012-2728-4http://link.springer.comopen access538.9Sol–gel coatingsPhotoluminescenceWaveguidesSilicaQuinineFísica de materialesFísica del estado sólido2211 Física del Estado Sólido
