Abstract :
A novel approach for optical filter implementation by tuning the plasmon resonance absorption of gold and silver nanoparticles in layer-by-layer (LBL) composite structures is presented. The LBL composite structures consisted of alternating layers of polyacrylic acid (PAA)-capped Au and PAA-capped Ag bi-layers. The results show clear spectrum tuning of green and blue peaks. Spectrum tuning can be extended when more metals or oxide nanoparticles are incorporated.
