The Influence of Doping of Fullerene Derivative (PCBM) on the Optical Properties of Vanadyl Phthalocyanine (VOPc)
نویسنده
چکیده
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. Keywords—Optical properties, spin-coating, optical properties, optical energy gap

Bilayer and trilayer organic films grown on Au(111) were studied by scanning tunneling microscopy (STM). Studies were carried out under UHV conditions with the sample cooled to either 80 or 100K. Cobalt(II)phthalocyanine [CoPc] was deposited from vapor onto Au(111), followed by vanadyl phthalocyanine, VOPc. CoPc coverages studied were 0.5 and 1 monolayer, while VOPc coverages were about 0.5 mon...
