This is demonstrated by studying the blue and red bands in the X-excited PP of the feldspar albite. The results indicate that at least part of the red luminescence is independent of the blue one. It is suggested that the blue emission results from the recombination of thermally released electrons with hole centres, while the red band is attributed to the recombination of holes with Fe2+ ions. Abstractde Für kinetische Analysen ist die Thermolumineszenz im allgemeinen zuverlässiger als die Phosphoreszenz. Die Phosphoreszenz kann aber zur Untersuchung der Beziehung der verschiedenen Spektralbanden mit gleichen kinetischen Parametern angewandt werden. Dies wird am Beispiel der mit Röntgenstrahlen angeregten blauen und roten Phosphoreszenzbanden im Albit dargelegt. Die Ergebnisse weisen darauf hin, daß wenigstens ein Teil der roten Lumineszenz von der blauen unabhängig ist. Es ist anzunehmen, daß die blaue Strahlung von einer Rekombination thermisch befreiter Elektronen mit Defektelektronenzentren herrührt, wohingegen die roten Banden auf eine Rekombination von Defektelektronen mit Fe2+-Ionen zurückzuführen sind.
