“…In doped PANI samples, the coexistence of free carriers and localized carriers results in polaron formation. Absorption bands close to energy values of 3.69 and 2.77 eV have also been reported by Sharma et al [39], who attributed them to the excitation due to the polaron band. The peak at 3.69 eV may be due to defects and upper conduction band excitations.…”

PANI/CdSe multiple-quantum wells (MQWs) and high-brightness MQW lightemitting diodes were grown by the chemical technique. An aniline monomer was electropolymerized to polyaniline (PANI) by using camphor sulphonic acid (CSA). Electrodeposited PANI, chemically synthesized cadmium selenide quantum dots (Q-CdSe), and nanocomposite films (PANI/Q-CdSe) were investigated in optical, structural, and morphological studies. A crystallite size of approximately 1.9 nm was calculated from the (111) diffraction peak of Q-CdSe using Scherrer's formula. Multiple peaks in photoluminescence (PL) of PANI/CdSe MQWs and in electroluminescence (EL) of MQW light-emitting devices (LEDs) were observed at room temperature. High-brightness LEDs emitting at 480 nm were successfully fabricated with an output power well above 0.2 mW at 10 mA and with a forward voltage of less than 0.85 V.

“…5. In all P(An-co-ABSA) copolymers, the formation of globular features (with and/ or without cavities), typical of doped PAn [36,37], can be observed, which had different diameters and different distribution densities and were more dense at the increased polymerization rate.…”

Self-doped conducting polyaniline (PAn) films were deposited on passive stainless steel (SS) AISI304 substrates by cyclic potential sweep deposition from aqueous mixed monomer solutions of aniline (An) and different aminobenzenesulfonic acids (2-, 3-or, 4-aminobenzenesulfonic acid, ABSA), without the presence of a supporting electrolyte. Two different An concentrations were examined (0.01 and 0.05 M), while the concentration of each ABSA used was kept constant at 0.
