Imidazolium based ionic liquids as novel benign media for liquid-dye laser systems

Room temperature ionic liquids (RTILs) have emerged as nature-friendly media suitable for various applications. In this work, Optical absorption, fluorescence behavior and fluorescence lifetime of three rigorously purified imidazolium ionic liquids, 1-butyl-3-methylimidazolium chloride (BMIM Cl), 1-Butyl-3-methylimidazolium tetrachloroaluminate (BMIM AlCl4), 1-Butyl-3-methylimidazolium tetrafluoro-borate (BMIM BF4) are studied in the neat...
