Abstract

NaCl crystals activated with copper were prepared either from the melt or from an aqueous solution. They were coloured either photochemically or additively. The absorption, luminescence and electron emission were then measured on such crystals. The experimental results show the cause of the different results obtained by different authors and what conclusions can be drawn for the elaboration of models of luminescent centres.
