BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.
The principle of light emission in the chemiluminescence system of the present invention itself is considered to be the same as that of a conventionally known chemiluminescence system. Based (peroxalate chemiluminescence).

That is, a reaction between oxalate and hydrogen peroxide generates a light emitting intermediate (peroxide), and the light emitting intermediate causes the fluorescent substance to emit light intensely. Specifically, 1,2-dioxetanedione or substituted 1,2-dioxetanedione is generated from a peroxide by a chemiluminescence reaction (oxalate ester chemiluminescence) between oxalate and hydrogen peroxide, and this is combined with a fluorescent substance. A charge transfer complex is formed between
From this, it is decomposed into the excited fluorescent substance and carbon dioxide. Such a reaction is promoted by the action of a catalyst. Therefore, in the present invention, the conventional liquid A (fluorescent liquid)
And the components constituting the liquid B (oxidizing liquid) can be used.
