Abstract
PURPOSE: To improve the residual image performance, by coating or adding isotope or radioactive substance to the signal electrode.
CONSTITUTION: In general, the energy conversion of the photo conductive layer 3 is possible with the incidence of light in addition to radioactive emission. Isotope or radioactive substance is coated or added internally to the transparent conductive film being the signal electrode 2 and radioactive rays are emitted on the photo conductive layer 3. Further, the conductive film 2 is formed with the raw material mixing the antimony chloride taking radioactive isotope, for example, 125Sb having 2.7 years for period of half decay as the major constituent to the tin chloride by 0.3%, and cadmium or selenium is formed as the main constituent for the photo conductive layer 3, allowing about 15nA of dark current and to imorove the residual image performance with sufficient bias light.
