Abstract

We report our results on the effect of incorporation of inorganic fullerene like nanoparticles (IF) and inorganic nanotubes (INT) of WS 2 into hybrid LED device structures. To disperse into a uniform fashion, the semiconducting INT/IF WS 2 NTs were functionalized with SDS (sodium dodecylsulphate). The IF/INT WS 2 nanotubes were used in combination with PEDOT:PSS and P3HT to realize the following LED device structures: ITO/(PEDOT:PSS):(WS 2:SDS)/P3HT/LiF-Al; ITO/PEDOT:PSS/P3HT/WS 2:SDS/LiF-Al. Morphological, optical and electrochemical analysis were performed to obtain the HOMO and the LUMO energy levels to hypothesize the most efficient device structure. The spectral positions of the electroluminescent bands were found out to be device-dependent and exhibits blue shift when the proposed nanostructure is dip coated on top of P3HT. Electro-optical analysis indicate that the WS 2:SDS based P3HT/semiconductor film can improve the charge recombination probability owing to its dual functionality as hole blocking layer and electron injection moiety. © EDP Sciences, Società Italiana di Fisica, Springer-Verlag 2012.
