Chemical Route

Surface Plasmon Resonance (SPR) is an attracting property of certain transition metals when they are synthesized in nano-range giving rise to promising optical applications. However, most SPR and associated applications are limited to the noble metal nanoparticles, which limits their potential due to high production cost. We report surface plasmon resonance in copper-copper oxide core-shell quantum dots synthesized via chemical route studied by using UV-Visible spectrophotometry. Tuning of the plasmonic resonance with respect to the particle diameter is achieved by an inexpensive all chemical route. Photoluminescence measurements also support the data. This size reduction leads to remarkable changes in its optical response as compared to the bulk metal. The results point towards applications of these materials in tunable SPR based biosensors.

AbstractOne-dimensional grating with 400 nm pitch was fabricated on a SiO2 glass surface. The grating was applied for detection of fluorescence excited by the electric field of the grating-coupled surface plasmon resonance and highly sensitive observation of fluorescence image by optical microscope. 40-times of fluorescence enhancement was obtained under optimal condition after our systematically investigating depth and duty ratio dependent behavior.
