Abstract
A chemiluminescent system and device is disclosed wherein a first polymeric sheet having a shaped cavity therein is sealed around its periphery to a second polymeric sheet and the cavity contains a cured PVC plastisol having admixed an oxalate solution and finely divided semiconductor laser crystals and a sealed receptacle containing a liquid component of a chemiluminescent activator. Placed over the plastisol or container is a light filter having a dye or dyes, pigment or pigments compounded into the filter, the dyes or pigments are chosen from those that absorb certain parts of the spectrum such that all light emissions up to 1050 nm are absorbed and anything beyond 1050 nm is transmitted. The devices generate a chemiluminescent light at wavelengths chosen to stimulate the semiconductor laser crystals. The semiconductor laser crystals absorb the chemiluminescent light and re-emit energy at wavelengths in the IR. By choosing the proper light absorbing dyes or pigments in the filter element, the emitted wavelength(s) that the activated device emits can be between 1 micron and 2.5 microns but no visible light.
