Research output: Contribution to journalArticlepeer-review


Tin oxide nanoparticles (2-5 nm) have been structured using CTAB surfactant into mesoporous mpSnO2 materials that exhibit lower electrical resistivity than the precursors SnO2 nanoparticles and over nine orders the magnitude lower than that of mesoporous MCM-41 silica. The superior performance of these conductive mesoporous mpSnO2 materials as hosts is clearly manifested by the fact that a conjugated polymer with 2,5-dimethoxyphenylenevinylene structure emits light at voltages below 10 V direct current when incorporated in mpSnO2 materials, but not in analogous mesoporous MCM-41 silica or when adsorbed on the nonporous precursor SnO2 nanoparticles.
