Scanning microscopy, used to investigate cathodoluminescence of a CdS crystal. leads to two important results : Only some parts of the crystal are luminescent (those where concentration of primary defects is high). In the spectral region explored (from ,3 000 to 6 000 Å) emission from some of these zones is polychromatic whereas others emit one wave length only.La technique de microscopie par balayage, appliquée à l'étude de la cathodoluminescence d'un cristal de sulfure de cadmium conduit à deux résultats importants : Seules, certaines régions du cristal (celles où la concentration en défauts primaires est élevée) participent à l'émission lumineuse. Dans le domaine spectral exploré (de 3 000 à 6 000 Å) certaines de ces zones émettent plusi...
