Sodium chloride crystals activated with copper were prepared either from the melt or from an aq. solution. They were colored either photochemically or actively. The absorption, luminescence, and electron emission were then measured on such crystals. The exptl. results show the cause of the different results obtained by different authors and the conclusions that can be drawn for the elaboration of models of luminescent centers.
