Abstract
396,601. Fluorescent screens. SIEMENS-REINIGER-VEIFA GES. FœR MEDIZINISCHE TECHNIK, 58, Mohrenstrasse, Berlin. Dec. 7, 1932, No. 34694. Convention date, Dec. 16, 1931. Addition to 372,827. [Class 98 (i).] To obviate loss of brightness, the active layer of the screen of the parent case, or its binding medium, is coloured with a colouring matter which selectively absorbs part of the fluorescent light and so alters the spectral composition of the emitted light. Best results are obtained when the emitted light is yellow or yellowish-green, corresponding with maximum colour sensitivity of the eye. Reference is made to zinc silicate and cadmium tungstate as luminescent materials, and examples are given of screens made from cadmium tungstate with a cellulose ester binding medium and coloured with brilliant green, fluorescein, quinoline yellow, auramine, chrysodine or iodine ; also of the use of coloured natural or synthetic resins as binding media, alone or mixed with other coloured or uncoloured binding media, e.g. orange or ruby shellac solutions alone or combined with cellulose ester solutions.
