White emission of polymeric luminescent compositions doped with boron chelates

Multicomponent polymeric luminescent compositions doped with $\beta$-diketonates of boron difluoride were obtained, which can be used to produce white light by cascade radiative energy transfer. The white light is obtained by using the RGB model. The compositions containing four luminophores showed high color rendering values (color rendering index $>$ 80, 2776 K). Two luminescent transitions were realized in the obtained compositions for the red dye (R): $S_1\to S_0$, associated with cascade radiative energy transfer along the chain of luminophores, and $S_2\to S_1\to S_0$, directly excited by UV radiation. The luminous characteristics of the obtained compositions indicate the possibility of using polymeric luminescent compositions doped with $\beta$-diketonate boron difluoride in emergency and indoor lighting devices.
