Abstract
The luminescence properties of boron difluoride enaminedibenzoylmethanates and their oxygen analogs in solutions and crystals have been investigated. At the transition from diluted solutions to concentrated ones and crystals, a significant bathochromic shift in the maxima of the luminescence and excitation spectra has been observed. It has been established that the luminescence of crystals and concentrated solutions is of an excimer nature.
