Patent ID: 7312867

Claim:
A device for the detection of at least one luminescent substance, with a radiation source for the emission of excitation radiation on the at least one luminescent substance, whereby the excitation radiation has at least one excitation wavelength at which the luminescent substance is excited to emit luminescent radiation, and with at least one radiation receiver which is insensitive to the excitation radiation, for the detection of the luminescent radiation, whereby the luminescent substance is located in the interior of a measurement chamber which is essentially impermeable to the radiation to which the radiation receivers are sensitive, and whereby the radiation source is located outside the measurement chamber such that the excitation radiation is injected through a wall area of the measurement chamber that faces the radiation source and is transparent for the excitation radiation through the measurement chamber into the interior of the measurement chamber, wherein the wall area is formed by a semiconductor substrate and that the at least one radiation receiver is integrated in the form of a semiconductor assembly into the semiconductor substrate.
