CdSe nanorods (NRs) are assembled using hydrothermal method using polyethylene glycol as a surfactant. The diameter and the length of the rods are found to be in the ranges of 10–30 and 80–210 nm, respectively. Besides, the CdSe NRs exhibit hexagonal structure with a crystallite size of 9.61 nm. Different concentration of CdSe NRs are mixed with poly [2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV). The structural features of the nanocomposites in the form of thin films prepared by spin-coating technique are studied by using of X-ray diffraction, field emission scanning microscope and atomic force microscope. The surface roughness of the MEH-PPV is calculated as 5.4 nm, which is significantly increased by the addition of CdSe NRs. Besides, the transmittance and the reflectance of the nanocomposite films are measured at the normal incidence of the light over wavelength range 200–2500 nm. The optical functions such as absorption coefficient and refractive index of the films are calculated and analyzed. The optical band gap of MEH–PPV is determined as 1.95 eV and is decreased with increasing CdSe NRs content. In addition, the single oscillator model is used to evaluate the optical oscillator parameters. Finally, the ratio of the free carriers to their effective mass is found to increase by increasing CdSe content.
