A device for a radiation detector includes a main body, which includes a material G and is at least partially provided with a coating. The coating has at least a first layer with a material A1. The material G of the main body can be excited by a primary radiation impinging on the coating, so that an x-ray fluorescence radiation is produced with an x-ray fluorescence spectrum, which has a maximum MG at an energy EG. Furthermore, at an energy E1, the material A1 has an absorption edge. In this case, the material A1 is chosen such that the relationships E1<EG and EG−E1≦̸4 keV apply. Also specified is a radiation detector, which has the device and a detector element, which is suitable for the detection of the primary radiation.
