Abstract:
A radiation detector receiving incident radiation from a source, said radiation detector comprising:(a) a radiation sensing element;(b) a layer of luminescent material interposed between said radiation sensing element and said incident radiation source;(c) said luminescent material being selected from the group consisting of polymers, oligomers, and copolymers, wherein the active material in said luminescent material forms the backbone of the polymer, oligomer or copolymer chain or the active material is a sidegroup attached to the polymer, oligomer or copolymer chain;(d) said luminescent material being selected to absorb radiation at a selected range of absorbing wavelengths, to luminesce at a selected range of luminescing wavelengths, and to be transparent at wavelengths longer than said selected absorbing wavelengths;(e) and said luminescent radiation being detected by said radiation sensing element.
