Composite wavelength converter

A detector element is for detecting incident x-ray radiation. The detector element includes a scintillation layer for converting the x-ray radiation into scintillation light and a photoactive element for converting the scintillation light into an electric signal. The photoactive element includes a first photoactive absorption layer contacted by an electrode, and a second photoactive absorption layer contacted by a counter electrode. Here, the scintillation layer is arranged between the first photoactive absorption layer and the second photoactive absorption layer.

The invention relates to an organic light emitting diode (OLED), also referred to as a light emitting diode, which comprises at least one substrate, one anode, one hole transport layer, one emitter layer, one cathode and one encapsulation. It is proposed that an energy carrier, which supplies the voltage that causes the OLED to emit light, be integrated into the OLED. The energy carrier can be a battery (energy storage device) or an energy converter (photovoltaic element).

Organic light emitting diode, method for the production thereof and uses thereof

A device to measure a radiation dose, in particular an x-ray radiation dose, which absorbs radiation and provides an absorption-conditional output signal representing a measurement for the dose, has at least one absorption structure disposed on a foil-like carrier, made from thin-film layers disposed on top of one another that form at least one thin-film diode structure that supplies the output signal.

Device to measure a radiation dose

An X-ray detector is for a CT device and includes a phosphor layer for generating electromagnetic radiation as a function of the occurrence of X-radiation, and a photodetector layer for detecting the electromagnetic radiation generated by the phosphor layer. The phosphor layer includes ceramic material and the photodetector layer includes organic material. A process is further for producing an X-ray detector, including the steps of producing a phosphor layer from a ceramic material and applying a photodetector layer made from an organic material to the phosphor layer via a spinning, printing or beam/jet process or by sticking it on as a film. It is optionally possible to provide a further process step for polishing the surface of the phosphor layer before applying the photodetector layer.

The invention relates to an intelligent color system that recognizes the ambient color and adapts its color accordingly according to the chameleon effect. The inventive system is obtained by combining an electrochromic color system with a semi-transparent array of photodetectors, for example combinations of individual pixels that are sensitive for the different colors (red, green blue), said array being superimposed on the electrochromic color system.
