description A light-reflecting material of a radiation detector, which also comprises photo-detecting elements and imaging elements adjacent to the photo-detecting elements, is provided. Typically, epoxy resin is used as the light-reflecting material. A tough, pliable resin may be used for the photo-detecting elements. This has the advantage of reducing thermal stresses inside the radiation detector, thus reducing the risk of delamination due to e.g. temperature shifts. Moreover, the tough, pliable resin preferably also has a low refractive index, which may increase the scattering co-efficient of the resin as compared to epoxy resin, which has a refractive index of 1.58. The layer thickness of a low-refractive index resin may thereby be reduced as compared to the layer thickness of epoxy resin for a given level of optical crosstalk. Preferable resins are silicon resins and resins of thermoplastic fluoropolymers.
