Abstract
The invention is drawn to a method of using nanoparticle aggregates to form sensors and optical filters. Properly sized (60 and 200 nm) nanoparticle aggregates with cores having a sulfur-oxygen molecular species and a shell with a surface in contact with the core are obtained. Those nanoparticle aggregates have a first resonance profile to wavelengths between 350 nm and 1075 nm. A modified resonance profile for those nanoparticle aggregates is determined. The nanoparticle aggregates are then selectively sized by irradiating them with electromagnetic energy at sufficient intensity and spectral content to modify the first resonance profile towards the modified resonance profile. The resulting nanoparticle aggregates can be used as sensors or optical filters at a selected wavelength.
