Fluorescence of tetraphenyl-butadiene in the vacuum ultraviolet.
Tetraphenyl-butadiene is a useful alternative to sodium salicylate as a fluorescent wavelength converter for detectors in the vacuum uv. Measurements of the fluorescence efficiency of TPB relative to sodium salicylate over the wavelength range 735-3160 A are presented, and the application of TPB coatings to image tube detectors is discussed. Over the entire wavelength range studied TPB had a higher fluorescent efficiency than sodium salicylate.
