Effect of Forster resonance energy transfer on the photoluminescence of PPy-ZnO composite

Synthesis, Characterization and Evaluation of Supercapacitive Response of Dodecylbenzenesulphonic Acid (DBSA) Doped Polypyrrole/Zirconium Dioxide Composites

“…The ring's C-N stretching vibration is represented by the band at 1452 cm −1 in the PPy spectrum [21]. The C-N in-plane band is at 1290 cm −1 , and the C-H bending modes are at 1164 cm −1 and 1031 cm −1 [21,22]. The C-C and C-H out-of-plane deformation vibration bands are at 963 and 891 cm −1 , respectively [21,22].…”

Except for the C-C, C-N and C-H bending modes of the pyrrole ring, the PPy/ZrO 2 composite spectra generated with various ZrO 2 weights displayed superimposed absorption bands of both components [21].…”

“…Because of their rapid redox kinetics and perfect capacitance, transition metal oxides were widely employed to improve the PPy's cyclic stability [17,18]. Different researchers synthesized nanocomposites of PPy with numerous MOs, including TiO 2 [19], Fe 2 O 3 [20], SiO 2 [21], ZnO [22] and CeO 2 [23], due to the large potential of CPs and polymers doped with inorganic metal oxides (MOs), which increase the performance of materials in many applications. High electron affinity, better mechanical characteristics, and high electrical conductivity may all be achieved by doping MOs in CPs [24].…”
