Supplementary Material

The Supplemental Material provides additional spectroscopic and material characterization data (X-ray diffraction, Fourier Transform Infrared spectra and Thermo Gravimetric Analysis), as well as higher resolution renderings of the TEM images. Also included are discussions of the optical technique for assessing chemical robustness of the infrared dyes and details on the calculations of the number of attached dye molecules per nanoparticle.
