✦ Synopsis

For the first time, the photoluminescence characteristics in the classical malonic acid Ce( IV) /Ce( III) Belousov-Zhabotinsky (BZ) reaction over an extended excitation and emission wavelength range are shown. It has been found that the observed photoluminescence in the BZ system can be related to the fluorescence of the isolated Ce(II1) ion. Possible phase relationships between the oscillatory photoluminescence and Ce( III) oscillations due to an 'inner filter effect' are discussed. No oscillatory chemiluminescence could be detected in this system.

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

## Abstract The adaptive synchronization scheme proposed by John and Amritkar was employed into the Belousov‐Zhabotinsky (BZ) 4‐variable‐Montanator model system. By the parameter adjustment, chaos synchronization has been obtained. Through calculating the transient time, the optimal combination of
