Using IR absorption and Raman spectroscopy we have analyzed the incorporation of Cu in SiO@sub 2@ matrix in samples prepared by the sol-gel method. Samples contain Cu at 30 %wt and were studied as a function of annealing temperature. It is found that the heat treatments have a remarkable influence on the structure. With this analysis we inferred that the final structure of the sample contain dioptase-like structures (Cu@sub 6@[Si@sub 6@O@sub 18@]*6H@sub 2@O).
