Platinum silicide detector

Miscellaneous. Chloroplatinic acid is used in the production of automobile catalysts. Platino-type prints based on reduction of Pt(II) to Pt(0) by a photosensitive reducing agent such as iron(III) oxalate are used in art photography (261,262). Infrared imaging devices based on a platinum siLicide detector have been developed (263).

Several other detectors are available for use in the near-IR. Cooled PbS, Ge, InGaAs, InSb, and platinum silicide have been investigated as detectors for use in FT-Raman. Present commercial instrumentation uses an InGaAs detector. For a discussion on detectors for use in FT-Raman, see Refs. 5 and 9. 

There are two major detector materials in the near infrared, mercury cadmium telluride (Hg Cd Te), and indium antimony (In Sb), although some lower efficiency detector arrays have been made with platinum silicide (PtSi). This wavelength region was the first to utilize arrays and is the most developed to date. Part of this has been due to the development in the early 1990s of Hg Cd Te arrays for the NICMOS on the HST. The NICMOS arrays contained 256 X 256 elements. Currently, 2048 x 2048 arrays of both Hg Cd Te and ln Sb are under development.
