Abstract
Abstract This invention relates to a packaged luminescent material, and more particularly to a combined package of a chemiluminescent agent as the ''''fuel,'''' and an activating agent therefor, wherein the fuel and activating agent are maintained in close association but separated from each other by a barrier medium to prevent interaction before the same is desired. When the barrier medium is ruptured, or otherwise broken down, either deliberately or unintentionally, a reaction occurs between the chemiluminescent agent and the activating agent with the emission of visible light, without, however, the generation of any appreciable amount of heat.
