Abstract
The design of a vacuum ultraviolet spectrofluorimeter for the measurement of luminescence from thin films is described. The instrument uses a pulsed continuum light source and a specially built detection system. The wavelength of excitation is selected by a double-grating monochromator of high spectral purity and large aperture. The excitation bandwidth employed may be adjusted without change of central wavelength or of sample illumination. Spectra are shown for thin films of anthracene and results are also cited for polyolefins and DNA films.Keywords
