Hassan Sayyad}, country = {}, institution = {}, abstract = {This paper presents a spectroscopic study on doping of Vanadyl pathalocyanine (VOPc) by [6,6]-phenyl C61 butyric acid methyl ester (PCBM). The films are characterized by UV/Vis/NIR spectroscopy. A drastic increase in the absorption coefficient has been observed with increasing dopant concentration. Optical properties of VOPc:PCBM films deposited by spin coating technique were studied in detail. Optical band gap decreased with the PCBM incorporation in the VOPc film. Optical band gap calculated from the absorption spectra decreased from 3.32 eV to 3.26 eV with a variation of 0–75 % of PCBM concentration in the VOPC films.}, journal = {International Journal of Physical and Mathematical Sciences}, volume = {5}, number = {10}, year = {2011}, pages = {1552 - 1555}, ee = {https://publications.waset.org/pdf/9128}, url = {https://publications.waset.org/vol/58}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 58, 2011}, }
