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