Optoelectronic properties of DNA thin films implanted with titania nanoparticle-coated multiwalled carbon nanotubes

摘要: Rendering the unique features of individual nanoscale constituents into macroscopic thin films remains technologically challenging; engineering these habitually compromises their inherent properties. Efficient, environmentally benign, and biodegradable DNA cetyltrimethyl-ammonium chloride-modified (DNA-CT) (TFs) implanted with titania nanoparticle-coated multiwalled carbon nanotubes (MCNT-TiO2) are prepared by a drop-casting technique. The energy dispersive X-ray spectroscopy studies DNA-CT TFs MCNT-TiO2 identifies various elements (C, O, N, P, Na, Ti) via quantitative microanalysis. photoelectron, Raman, Fourier-transform infrared (FTIR), UV-visible absorption spectra show changes in chemical compositions functional groups associated binding energies, enhancement characteristic Raman bands, intensity peak shifts FTIR UV-Vis-NIR respectively. PL indicate an transfer measured samples, quenching indicates decrease recombination efficiency. Lastly, we measure conductivity, which increased increasing concentration due to better connectivity MCNT-TiO2. By using materials, optoelectronic properties easily tunable, enabling several multidisciplinary science applications, such as photonics, electronics, harvesting, sensors.Rendering indica...
