Emission and absorption spectra of BSB-Me dichloromethane solution and BSB-Me nanocrystal water dispersion. Emission spectra of BSB-Me dichloromethane solution (a) and BSB-Me nanocrystal water dispersion (b). The excitation wavelength was 324 nm for each spectrum. The integrated intensity (areas) of the spectra was calculated as 528,826 for (a) and 58,884 for (b). Inset: the absorption spectra of the BSB-Me dichloromethane solution (c) and BSB-Me nanocrystal water dispersion (d), where both samples had the same optical density of 0.045 at 324-nm wavelength.
