28,280 IMPROVED CHEMICAL LIGHTING DEVICE ABSTRACT OF THE DISCLOSURE In chemical light devices comprising a chemi- luminescent mixture with a first fluorescer contained in a transparent or translucent container, a second fluor- escer is incorporated in the walls of the container to shift at least part of the emissions from the device from the shorter wavelength emission of the first fluorescer to a longer wavelength emission of the second fluorescer. The second fluorescer has an absorption spectrum substan- tially overlapping the emission spectrum of the first fluorescer. The shift is usually about 20 to 100 nano- meters and may be as much as 200 nanometers.
