    摘要: This disclosure defined by this invention sets forth an X-ray detector including a scintillator. The scintillator is formed with a doped alkali halogenide and is constructed with an array of photodiodes including at least one photodiode containing a semiconductor material with a color transformer. The color transformer contains a photoluminescent phosphor and may be arranged between the scintillator and the array of photodiodes. One benefit of the scintillator, and an x-ray detect which includes the scintillator, is that it enables a larger part of the X-radiation to be used for image analysis.

    摘要: A lamp vessel is made from a material which absorbs short-wave UV radiation. In addition, the luminescent screen comprises cerium-activated lunthanum phosphate and a luminescent substance having an emission band whose maximum is situated in the wavelength range from 340 nm and whose half-value ranges between 35 nm and 80 nm. The emission spectrum of the lamp for wavelengths below 400 nm corresponds closely to the solar spectrum while the lamp also has a high erythema L light output.
