Atomic and Molecular Spectroscopy with UV and Visible Superbright LEDs

Our most recent absorption and emission experiments with heavy alkali vapor using super bright light-emitting diodes from NICHIA, LUMILED and OSRAM will be presented. UV LEDs together with LEDs in the visible spectral region present invaluable narrow-band continuum light source for very precise absorption measurements. We used all-sapphire cells and heat-pipe oven cells in usual absorption arrangement with high resolution scanning monochromators. Beside self-broadened alkali resonance lines, we investigated molecular bands and diffuse bands of alkali dimers. A number of applications, especially in dentistry will be also presented.
