A dielectric barrier discharge in mixtures of xenon and iodine to provide intense narrow band ultraviolet (UV) radiation at λ=253 nm (XeI*) has been investigated. The characteristics of the emission spectra of the excited dimer (excimer) and UV intensity formed from mixtures of xenon and iodine for different total gas pressures are reported. The absolute UV output power of the XeI* lamp has been determined using actinometry based on the photohydrate of uridine. The electrical power dependence of the UV intensity generated as well as the conversion efficiency of the lamps has also been studied. Conversion efficiencies (from input electrical to output optical energy) as high as 22.5% have been achieved for an electrical power input of 70 W, with 15.75 W of optical output being generated.
