Abstract

In the present research CdSe quantum dots were reinforced into as-polymerized polyaniline (PANI) to yield polymer nanocomposites. The lattice constants of CdSe and CdSe in the nanocomposites were calculated to be 6.24 Å and 5.44 Å, respectively for cubic phase. The surface morphology of pure PANI showed agglomeration of spherical particles. The EDAX spectrum confirmed the presence of compositional elements of PANI and CdSe in the nanocomposite. Ohmic behavior of composite evidenced the possibility of its use in P-N junction diodes. The morphological observations revealed that DC conductivity of PANI/CdSe nanocomposites was higher than that of the PANI. The value of short circuit current also increased from 0.3 [A (cm)−2] to 150 [A (cm)−2]. The observed findings revealed that the present material has potential to fabricate protective devices, P-N junction diodes, electronic devices, and gas sensor devices.
