Abstract

1,186,541. Light modulators. AMERICAN CYANAMID CO. 23 Feb., 1967 [25 Feb., 1966; 14 March, 1966; 25 July, 1966; 7 Dec., 1966], No. 8755/67. Headings H4F arid H5R. [Also in Divisions G5 and H1] An electro-optical device, Fig. 6, comprises an electrochromic layer 26 positive or negative photoconductive layer 50, e.g. CDS and insulating layer 34 between electrodes 24, 28. For radio-photographic applications layer 50 may be an ionizing radiation conductive material, the radiation through image plate 52 being light, X-rays, electron beams, gamma rays, or beta rays. Persistent electrochromic materials are referred to which remain in the absorptive state on removal of the electric field and may be reverted to the initial state by the application of a reverse polarity field or by short-circuiting. The radiation sensitive layer and electrochromic layer may be flexible or rigid films as in a roll film or plate camera. In Fig. 7 (not shown) a writing electron beam may replace the stylus (24<SP>1</SP>). In these devices the electrochromic material comprises a transition metal compound in which the transition metal can exist in different stable oxidation states within the temperature range- 50‹ to 125‹ C., the different oxidization states having different electromagnetic radiation absorption characteristics. The transition metal compound is defined as containing a transition metal taken from groups IB, IIB, IIIA, IIIB, IVA, VA, VIA, VIIA and VIII and an element from groups VI B and VIIB. A wide range of materials is disclosed.
