Shining a new light on materials

University research finds new applications for hybrid materials.

Research has shown that hybrid, photoactive materials respond differently when exposed to excitation light. The work, undertaken at UPV/EHU-University of the Basque Country, Spain’s Department of Physical Chemistry, could have applications in fields such as optics and biomedicine.

Rebeca Sola, from UPV/EHU, obtained hybrid materials, as part of a PHD thesis, by incorporating fluorescent dyes into channelled inorganic structures, among other methods. This process makes the dyes more stable against degradation and improves overall rigidity. 

Sola commented, ‘Highly fluorescent materials, in which the dyes are found to be ordered, were obtained, thus providing a highly anisotropic response to the linearly polarized light.’ In essence, materials respond according to the direction of the polarisation of the incident light.
