From: Imaging of X-Ray-Excited Emissions from Quantum Dots and Biological Tissue in Whole Mouse
X-ray-excited endogenous radioluminescence from mouse cadavers with and without QDs. X-ray excitation at 55 kVp. The intensity scale has been set to accentuate the faint end of the intensity scale. (a,b) Partially depilated, furred mouse with QD injection, orientation as for Fig. 2. (a) (red) 700 nm narrowband (FWHM 70 nm) filter accentuating 715 nm QD emission. (b) (cyan) Broadband BG39 filter to accentuate endogenous emission at wavelengths < 600 nm. The distribution of endogenous radioluminescence in (b) indicates it arises mostly from the fur. (The bright spot in the leftmost quarter of image (b) is a detector artefact). (c,d) Rump of (left) nude and (right) furred mouse without QDs. (c) Broadband red (RG665) image. (d) Broadband blue (BG39) image showing that the furred mouse emits more strongly than the nude mouse in the 320–660 nm band. The curved dark band is the silhouette of the nude mouse tail (not irradiated) blocking the emission from the furred mouse.
