Abstract

Surface morphology and optical properties in term of Surface Plasmon Resonance (SPR) of 4-methylbenzenthiol capped gold nanoparticles using Langmuir-Schaefer (LS) technique were studied. 1 and 3-layers nanoparticle films with 1mg/ml in concentration have been prepared. Gold nanoparticles films were annealed at 200oC for 1h. Film’s morphology and SPR before and after annealing were investigated by Atomic Force Microscopy (AFM) and UV-Vis spectrophotometer respectively. After annealing, a drastic change in the shape and size of the nanoparticles was revealed; however, no significant effect of film thickness on the gold nanoparticle size was observed. UV-Vis spectra showed reduction in intensity and decrease in width of SPR peaks as a result to annealing. Blueshift in SPR position has been observed for both heat treated films.
