Abstract : The fluorescence of purified and unpurified Rhodamine B vapors was observed using for excitation all the lines of an argon ion laser. The compound was heated in the side arms of a 43-cm long tube evacuated to about 1/1,000,000 torr. The temperatures of the side arms were varied from 200 to 400C. The emission band was very broad, characteristic of vapor phase fluorescence and its peak was at approximately 508-nm. No appreciable fluorescence was detected from either purified or unpurified Rhodamine 6G vapor. Absorption measurements made on this compound indicated that no fluorescence was detected because of self-absorption. (Author)
