Effect of nature of gas on luminous and spectral-time characteristics of tubular pulsed lamps

Pulsed Sources for Atomic Fluorescence

“…Values of approximately 50% can be achieved with xenon, and the radiative efficiency increases by increasing the peak current density. The spectral distribution of the radiation emitted depends upon the current density and the pulse duration: short pulses and high current densities shift the spectral output toward the ultraviolet region (18,19). A great variety of lamp geometries (linear, miniature and capillary types, annular, helical, pi-shaped) are available, but the best arrangement for fluorescence would be given by short arcs or essentially point sources.…”
