VUV sugárforrás fényteljesítményé nek meghatározása kémiai aktinometriával

Translated title of the contribution: Measuring the intensity of VUV light source by chemical actinometry

Abstract

Chemical actinometric methods were developed for measuring the light power of a home-made Xe-excimer lamp in the gas phase and aqueous solutions. It was found that the quantum yield of ozone formation at a given light power varied with the ozone concentration and the oxygen content of the gas applied. Calculations led to a simple kinetic model by which the ozone production was simulated. VUV photolysis of oxygen-containing water produces hydrogen peroxide. Its formation rate depended on the light power and dissolved oxygen concentration of the irradiated pure water. Kinetic calculations, evaluated by applying a simple chemical mechanism, confirmed that following the hydrogen peroxide formation was adequate for light power determination.
