Title
(EN) X-RAY PHOTOCONDUCTIVE COMPOSITIONS FOR X-RAY RADIOGRAPHY
(FR) COMPOSITIONS PHOTOCONDUCTRICES PAR RAPPORT AUX RAYONS X POUR RADIOGRAPHIE AUX RAYONS X
Abstract
(EN)
New x-ray photoconductive compositions are disclosed which are certain composites containing (1) inorganic clusters of VB-VIB semiconductors, VB-VIIB semiconductors, IIB-VIB semiconductors, IIB-VB semiconductors, IIIB-VB semiconductors, IIIB-VIB semiconductors, IB-VIB semiconductors and/or IVB-VIIB semiconductors and (2) polymers which are essentially non-carrier-transporting in the absence of x-rays. Also disclosed is an x-ray radiography apparatus which employs an image receptor which is a composite of certain inorganic clusters and polymers. A method is disclosed for enhancing the x-ray absorbing efficiency of a polymer which is essentially non-carrier transporting in the absence of x-rays and the x-ray photoconductivity of said polymer by doping the polymer with an effective amount of clusters having a size within the range of from about 0.001 $g(m)m to 10 $g(m)m.

Nouvelles compositions photoconductrices par rapport aux rayons X qui sont des composites contenant (1) des amas inorganiques de semi-conducteurs VB-VIB, de semi-conducteurs VB-VIIB, de semi-conducteurs IIB-VIB, de semi-conducteurs IIB-VB, de semi-conducteurs IIIB-VB, de semi-conducteurs IIIB-VIB, de semi-conducteurs IB-VIB et/ou de semi-conducteurs IVB-VIIB et (2) des polymères qui sont essentiellement non transporteurs de vecteurs en l'absence de rayons X. La présente invention concerne également un appareil de radiographie aux rayons X qui emploie un récepteur d'images constitué d'un composite de certains amas inorganiques et polymères. Elle concerne en outre un procédé permettant d'améliorer l'efficacité d'absorption de rayons X d'un polymère qui est essentiellement non transporteur de vecteur en l'absence de rayons X et la photoconductivité par rapport aux rayons X dudit polymère par dopage du polymère avec une quantité efficace d'amas dont la taille se situe entre environ 0,001 $g(m)m et 10 $g(m)m.
