N2 - Low threshold lasing of perylene and 9,10-diphenylanthracene has been achieved by means of energy transfer in binary solute solutions pumped by a nitrogen laser. The low absorption of these compounds to the 3371. A excitation radiation has been overcome by the mechanism of nonradiative dipole-dipole energy transfer. In addition, when a donor has a high molar extinction coefficient at 3371 Å and good spectral overlap characteristics with an acceptor, it can serve as an efficient donor for lasing even though it has a low fluorescence quantum yield.
