Abstract : Cadmium selenide (CdSe) nanoparticles formation were observed in thin films prepared through angle lifting deposition method and gas exposure. The thin film was prepared by mixing long chain polymer, poly(3-hexylthiophene)with stearic acid on de-ionized water containing cadmium (II) chloride in a hydrophobic bath to produce Langmuir layer. The layer was then compressed until it enters the solid phase, and subsequently transferred onto quartz substrate using the angle lifting deposition method. The thin film was then exposed to hydrogen selenide (H2Se) gas for 6 hours to create CdSe nanoparticles. Field Emission Scanning Electron Microscopy (FESEM) confirmed the presence of CdSe nanoparticles capped by polymer that act as ligand, hence limiting the CdSe size to 15-18 nm. EDX reported the weight percentage of cadmium and selenide in the thin film, as 9.64% and 13.53% respectively. Photoluminescence (PL) of the thin films before and after exposure show a thin film that has been exposed for 6 hours has reduced PL intensity as compared to unexposed samples. The decrease in the PL intensity indicates that efficient photo-induced electron transfer is likely. Hence, the thin film has potential to be used in electronic applications.
