L'émission électronique « spéciale », la luminescence et les centres colorés dans les cristaux phosphorescents anorganiques

Abstract
Several crystals with coloured centers show an effect, called by the author "special electronic emission ", which is observed after the excitation has ceased. Comparative study of thermoemission, thermoluminescence and absorption leads to results on the structure of the crystals. The used samples may be monocrystalline or pulverulent.
