Abstract
A photoluminescence measurement device may include: a sample holder; a detector configured to collect a photoluminescence signal; a processing unit configured to process a signal collected by the detector; and a support disposed facing a rear face of the sample holder, opposite to the front face, and on one face, called the main face, of which rests at least one radiation source for emitting light radiation illuminating the rear face and likely to be collected, by transparency of the sample holder with respect to the light radiation, by the detector.
Claims12
A photoluminescence or electroluminescence measurement device, comprising:
- a sample holder;
- a detector configured to collect a photoluminescence or electroluminescence signal emitted by a sample likely to be disposed on a front face of the sample holder;
- a processing unit configured to process a signal collected by the detector;
- and
- a support disposed facing a rear face of the sample holder, opposite to the front face, and on a main face, of which at least one radiation source rests for emitting light radiation illuminating the rear face and likely to be collected, by transparency of the sample holder with respect to the light radiation, by the detector,
- wherein, when a sample having a contour C rests through a first face on the front face of the sample holder, and so that the sample is circumscribed by an overflow zone of the sample holder, through which light radiation, likely to be emitted by the at least one radiation source, is likely to pass, and
- wherein the detector is also configured to establish mapping of light intensity of the radiation likely to pass through the overflow zone and of the photoluminescence signal emitted by the sample.
