Abstract

In the frame of this grant we intend to perform a research on a composite material based on carbon nanotubes (CNs) and inorganic semiconductings as zinc oxide (ZnO), which  can be used as active compound in the sensor technology and optoelectronic devices. A great attention will be paid to the synthesis procedures and characterization by optical methods of the final compound. For a duration of 3 years are proposed following scientific objectives to be carry out: i) producing and characterization by Raman scattering, ultraviolet-visible-near infrared (UV-VIS-NIR) absorption and photoluminescence (PL) spectroscopy of the blend consisting from single-walled carbon nanotubes (SWNTs) and ZnO nanoparticles; ii) modeling of  the PL properties of CNs/ZnO composite by selective chemical reactions between the metallic and semiconducting component of CNs with ZnO; iii) technological researches concerning the electrochemical and chemical synthesis of the SWNTs/ZnO composite material; iv) characterization by optical methods ( Raman scattering, UV-VIS-NIR and PL spectroscopy) and electronic  microscopy (transmission  electron  microscopy (TEM), scanning electron  microscopy (SEM)) of the SWNTs/ZnO material; v) testing and features of  SWNTs/ZnO hybrid materials as chemical sensor . Three routes are proposed to prepare of  the SWNTs/ZnO hybrid material: i) mechanic-chemical process, which imply mechanical motions/energy control chemical reactions to direct mixing of the ZnO with nanotubes, ii) chemical synthesis of  the ZnO  in the presence of  SWNTs; and iii) electrochemical synthesis of ZnO on the SWNTs electrode.
