文摘

It has been found that solid-phase interaction of anhydrous terbium(III) sulfate powder with xenon difluoride at room temperature is accompanied by chemiluminescence (CL). The formation of terbium( IV) and ozone in the course of the reaction has been observed spectrophotometrically. Two CL emitters, xenon in the Xe(I)* oxidation state (540, 580 nm) and Tb(III)* (490, 545, 590 nm), have been revealed. Emission by the former is observed at the beginning of the reaction. After the consumption of xenon difluoride, the emission is due to excited Tb(III) generated as a result of reduction of the Tb(IV) intermediate.
