Structural Modifications and Extended Spectral Response of CeO 2 /CoPc Nanocomposites for Potential Applications

CeO 2 /CoPc nanocomposites were synthesized by simple chemical method. Thermal behavior of these nanocomposites was studied by thermogravimetric and differential thermal analysis. The as‐synthesized nanocomposite samples were characterized by various techniques. A decrease in band‐gap energy together with an improved absorption intensity of the composite material confirms the role of the cobalt phthalocyanine in the absorption properties of CeO 2 /CoPc composite. This study confirms structural modifications and extended spectral response of the synthesized CeO 2 /CoPc nanocomposites. The results demonstrate that CeO 2 /CoPc nanocomposite samples are promising materials for organic light‐emitting diodes, solar cells, and optoelectronic devices.
