Abstract
The properties of stimulated emission of 1,3,5,7,8-pentamethyl-2,6-diethylpyrromethene-difluoroborate molecules in the film of porous aluminum oxide with were studied. It was established that the fluorescence intensity of the dye increases to a concentration of silver nanoparticles of C Ag = 0.42 * 10 −7 mol, and a further increase in the concentration of nanoparticles leads to the quenching of the fluorescence intensity. Plasmon resonance in silver nanoparticles in a film of porous alumina reduces the decay kinetic of fluorescence by a factor of 1.5. Stimulated emission of the fluorescence of the dye in the porosity film was detected at the short-wave maximum of the fluorescence band. It was established that the plasmon resonance in silver nanoparticles reduces the threshold of stimulated emission of a dye in a film of porous aluminum oxide 1.4 times, and the PCE of generation increases to a value of 0.4%.
