Project: Gels with innovative optical, magnetic and electrochemical properties

Acronym: Gels
Main Objective:
The main goal of the project is the study of relevant physical properties of new hybrid xerogels (doped with lanthanide or ferromagnetic ions). Those sol-gel derived materials, based on oxyethylene units grafted onto silica networks by urea and urethane cross-links, are efficient white light emitters due to the convolution of a long-lived emission originated in the NH groups of the urea or urethane bridges with shorter-lived electron-hole recombinations occurring in the nanometer-sized siliceous clusters. This feature will be exploited to obtain efficient white-light hybrids.
