FIG. 1.

Emission spectrum recorded for the nanoparticles under excitation with an intensity of . The inset shows the pump-power dependence of the interesting line measured under low intensities.

FIG. 2.

Schematic of the imaging setup. Light from a fiber-coupled laser is scanned in an array on the surface of the phantom. An air cooled CCD camera is used to capture an image for every scanned position.

Image of FIG. 3.
FIG. 3.

Images comparing the DY-781 dye and the nanoparticles with and without autofluorescence, along with plots showing the sums in the vertical directions. The white dots have been added artificially and represent the positions used for the excitation light. The left column shows the results using DY-781, and the right column shows the results using upconverting nanoparticles. (a) and (b) are taken without any added autofluorophores. (c) and (d) are taken with a background autofluorophore concentration of .
