The invention specifies a radiation detector for detecting radiation ( 8 ) according to a predefined spectral sensitivity distribution ( 9 ) that exhibits a maximum at a predefined wavelength lambda<SUB>0</SUB>, comprising a semiconductor body ( 1 ) with an active region ( 5 ) serving to generate a detector signal and intended to receive radiation, in which according to one embodiment the active region ( 5 ) includes a plurality of functional layers ( 4 a, 4 b, 4 c, 4 d) that have different band gaps and/or thicknesses and are implemented such that they ( 4 a, 4 b, 4 c, 4 d) at least partially absorb radiation in a range of wavelengths greater than lambda<SUB>0</SUB>. According to a further embodiment, disposed after the active region is a filter layer structure ( 70 ) comprising at least one filter layer ( 7, 7 a, 7 b, 7 c), said filter layer structure determining the short-wave side ( 101 ) of the detector sensitivity ( 10 ) according to the predefined spectral sensitivity distribution ( 9 ) by absorbing wavelengths smaller than lambda<SUB>0</SUB>. A radiation detector for detecting radiation ( 8 ) according to the spectral sensitivity distribution ( 9 ) of the human eye is also specified. The semiconductor body can be monolithically integrated.
