Near-1R region

As described in papers using gold nanoshells that have also shown surface plasmon bands in the near-1R region [36, 37], the targeted delivery of nanoparticles allows us to... 

Figure 34.9 shows an absorption spectrum from the abdomen of the mouse. There was intense absorption of hemoglobin in the visible region, and the onset of absorption of water in the near-1R region (>900 nm). The integral sphere was found to be useful in order to obtain the absorption spectra of the abdomen of a mouse. 

A lead sulfide photoconductor is the most widely used transducer for the near-1R region of the spectrum from 10,000 to 333 cm(I to 3 pm). It can be operated at room temperature. For mid- and far-lR radiation, MCT photoconductor transducers are used. They must be cooled with liquid nitrogen (77 K) to minimize thermal noise. The long-wavelength cutoff, and many of the other properties of these transducers, depend on the ratio of the mercury telluride to cadmium telluride. which can be varied continuously.
