Thermoluminescence

Thermoluminescence instruments are designed to investigate structure of energetic levels in the Photosystem II. Light-induced charge separation in the Photosystem II reaction centers results in accumulation of radical pairs that store the absorbed light energy. Heating induces recombination of these radical pairs and it triggers light emission and formation of characteristic thermoluminescence glow curves.

Thermoluminescence PSI Thermoluminescence instruments are designed to investigate structure of energetic levels in the Photosystem II. Light-induced charge separation in the Photosystem II reaction centers results in accumulation of radical pairs that store the absorbed light energy. Heating induces recombination of these radical pairs and it triggers light emission and formation of characteristic thermoluminescence glow curves. The shape and the peak position temperature of the different thermoluminescence bands provide valuable information about the energetic stability of the respective radical pairs as well as about the functioning of the Photosystem II reaction centers. Interpretation of the obtained data requires a through understanding of the charge pairs responsible for generating different thermoluminescence bands. High-temperature thermoluminescence appears as a result of accumulation of lipid peroxides and can be used as a simple and efficient tool to monitor oxidative stress in plants.
