Abstract

This report presents the synthesis and characterization of niobium doped TiO2 nanoparticle prepared by sol-gel immerse heater method and the deposition of MEH-PPV: Nb doped TiO2 nanoparticle. The mixed Nb-TiO2 with MEH-PPV were deposited at 6 different parameter which is 0wt%, 5wt%, 10wt%, 15wt%, 20wt%, 25wt% by spin coating deposition method. Then the thin film was characterized by electrical and optical properties, and surface morphology. The current-voltage measurements show the relationship between conductivity and resistivity of the thin film. Degree of slope determines resistance and resistivity values. For electrical properties, it was found that the conductivity of nanocomposites MEH-PPV: Nb doped TiO2 thin films increase as doping of Nb doped TiO2 is increase but it also have the limit. The U-V VIS measurement used for transmittance, absorption and optical band gap energy as optical properties. But for structural properties we used the field emission scanning electron microscopy. The electrical, optical and structural properties of these films have been studied.
