Abstract

Calcination of a scandium-O-phenylene-O-yttrium-O-phenylene hybrid copolymer under an argon atmosphere at 400–800 °C was performed. The calcined materials were found to be composed of nano-sized Sc2O3 and Y2O3 particles in the matrix of carbon clusters. ESR spectral examinations of the calcined materials suggest that a two-step electron transfer of Y2O3 → carbon clusters → Sc2O3 → carbon clusters took place to provide a photo-responsive oxidation–reduction function with an oxidation site at Y2O3 particles and a reduction site at carbon clusters.
