Abstract
The absorption of zinc sulphide powders, both pure and with various concentrations of activator, was measured in the region 3200-4800A by the diffuse reflection method. It was found that the long wave-length limit of the absorption band for a pure ZnS powder was at 3800A and that this limit moved to longer wave-lengths with increasing concentration of Ag activator. No evidence could be found of a secondary absorption peak characteristic of the activator.
