✦ Synopsis

Oscillating photoluminescence in the Ce(III)/Ce(IV) catalyzed Belousov-Zhabotinsky reaction is described. No quantitative data can be obtained from luminescence intensity measurements, due to quenching and inner filter effects. From lifetime measurements, it is possible to evaluate the quenching effect, which is attributed to bromate ions that oxidize the excited Ce(III) species. Some consequences are discussed.

At a certain temperature the malonic acid Belousov-Zhabotinsky reaction, which is simultaneously catalyzed by ferroin and cerium ions, can exhibit regular transitions between the ferroin oscillating and the cerium oscillating states. We believe that this is the first demonstration of transitions bet

The observation of photoinduced image formation in the alcohol-added ferroin-catalyzed Belousov-Zhabotinsky (BZ) reaction is reported. It is found that alcohol acts as a reagent that reduces the activation energy both of the ferroin-catalyzed and the Ce-catalyzed BZ reaction system and enhances the
