Abstract
Further support is provided for a model of the stimulation process in inorganic phosphors recently proposed by Luchner, Kallmann, Kramer, and Wachter. A reasonable identification of the center responsible for the absorption of stimulating radiation (the main feature of this model) is made for zinc sulfide phosphors containing copper, but it is shown that no identification can be made as yet of the absorbing centers responsible for most of the peaks of stimulation spectra so far observed. Many of the apparently incompatible published observations can be reconciled with the aid of previously unpublished work.
