Abstract

A radiation detector is disclosed, for the detection of radiation (8), with a given spectral sensitivity distribution (9), which has a maximum at a given wavelength lambdao, comprising a semiconductor body (1) with an active region (5), provided for detector signal generation and for the incident radiation. In one embodiment, the active region (5) comprises a number of functional layers (4a, 4b, 4c, 4d), with differing band gaps and / or thicknesses and embodied such that said layers (4a, 4b, 4c, 4d) at least partly absorb radiation at a wavelength greater than lambdao. In a further embodiment, a filter layer structure (70) is arranged after the active region, comprising at least one filter layer (7, 7a, 7b, 7c). The filter layer structure determines the short wave side (101) of the detector sensitivity (10), according to the given spectral sensitivity distribution (9), by means of absorption of wavelengths less than lambdao. A radiation detector for the detection of radiation (8), according to the spectral sensitivity distribution (9) of the human eye is also disclosed. The semiconductor body can be monolithically integrated.

Description

technical field

[0001] The invention relates to a radiation detector for detecting radiation according to a predetermined spectral sensitivity distribution, wherein the sensitivity distribution is at a predetermined wavelength λ 0 There is a maximum at , the radiation detector comprising a semiconductor body having an active region for detector signal generation and for radiation reception. In particular, the invention relates to a radiation detector for detecting radiation according to a predetermined spectral sensitivity distribution of the human eye. Background technique

[0002] In order to be at a predetermined wavelength λ 0 To detect radiation at a predetermined spectral sensitivity distribution with a maximum value, radiation detectors with specially adapted external filter arrangements, such as interference filters or monochromators, are often used. Such detectors are distinguished by a good match to a predetermined spectral sensitivity distribution, but are in mo...
