Abstract :
Thirteen layers of P3HT/stearic acid films have been deposited using angle lifting deposition technique onto ITO coated glass substrate at constant surface pressure. Gas exposure method was employed to embed semiconducting nanoparticles in the P3HT/SA matrixes. The isotherm of composite P3HT/SA shows a unique trend combination of small molecules of stearic acid and long chain polymer. UV-Vis result revealed the presence of CdS quantum dots in between P3HT/SA matrices. After subtracting the spectra before and after gas exposure, it was found that the CdS peak is at 420 nm, indicating the size of quantum dots created is around 4nm.
