Abstract: The nature of radiative transfer of electronic excitation energy from rhodamine 6G to oxazine 17 is determined. As a result of laser excitation, lasing in the acceptor (oxazine 17) is achieved due to absorption of donor (rhodamine 6G) luminescence by its molecules. The continuous tuning range of single-component ethanol solutions of rhodamine 6G and oxazine 17, and of a binary rhodamine 6G–oxazine 17 system with energy transfer, is determined.
