Biliproteins have extended the spectral range of fluorescent proteins into the region of maximal transmission of most tissues and are favorable for multiplexing, but their application presents considerable challenges.
Our previous measurements at 355 nm excitation have shown that the spectral range above ~600 nm does not contain useful information (see also measured results in [ 6, p. 28-12], [ 9]).The raw data consisted of 205 channels at 10 Hz sample rate.
The obtained composite structure has demonstrated photoluminescence in the spectral range of 500 800 nm.
Since the initial demonstration (Opt. Lett. 26 (2001 12455) the spectral range has been broadened by two orders of magnitude and the channel number has been improved by nearly one order of magnitude.
We selected amine terminated GNPs (Nanopartz) with a medium size of 20 nm, because their surface plasmon resonant (SPR) wavelength matches with the absorption spectrum of FNDs that has a strong absorption in the spectral range of 500-620 nm.
The spectra for these four stars have been normalized to one in the spectral range shown, but for clarity we have applied an offset of 0.2 between each spectrum.
The optical transmittance spectrum showed that the carbon thin film has >96% optical transmittance over the spectral range from 350 nm to 900 nm.
The new storage ring, which is called 'Metrology Light Source' (MLS), will mainly be dedicated to radiometry and technological development in the UV, VUV and EUV spectral range and will thus fill the gap in the spectral range that has opened up since the shut-down of BESSY I.
Besides, it has been shown recently that in the spectral range of Er3+ emission, another emission with nanosecond decay appears which, however, cannot be related to Er3+ ions.
Nitride semiconductors such as aluminum gallium nitride and gallium nitride have the widest spectral range of band gaps the energy required to move electrons through the material among all semiconductors, ranging from the infrared through the visible and into the deep UV range.
