2D Cooled CCD Imaging of Delayed Luminescence

Delayed luminescence is a weak light in the visible spectrum region, which decays hyperbolically after exposure to external light illumination of the sample. It has a diagnostic value, although its fundamental properties are not well understood yet. We constructed a chopper system, which allows the illumination of the object with 100 Hz pulses of light. We collected the DL emission data on cooled CCD for 2D imaging between pulses.
