“…It is important to emit white emission in certain concentrations of PHB solution. The compounds demonstration similar fluorescence bands have used for white light emitting diodes in the literature [18]. The high solution concentrations of PDEAHP and PHB light emit at peak wavelength forward from 500 nm.…”

“…β-Дикетонаты дифторида бора при вы-соких концентрациях способны образовывать эксимеры (димеры и тримеры) в растворах [2,3] и в полимерной матрице [4], что значительно повышает фотостойкость красителя [5]. Люминесценция эксимеров отличается значительным батохромным смещением спектра лю-минесценции относительно спектра поглощения люми-нофора, что позволяет уменьшить потери энергии в результате самопоглощения.…”

“…Возможно также образова-ние эксиплексов в результате взаимодействия молекул люминофора с ароматическими группами соседних мо-лекул [6]. Как показано в [3], изменяя концентрацию раствора β-дикетонатов дифторида бора можно управ-лять цветом люминесценции. β-Дикетонаты дифторида бора способны образовывать ярко люминесцирующие агрегаты, возбуждение которых происходит на длинно-волновом краю спектра поглощения [7].…”

“…White-emitting single-molecule systems with elegant molecular designs, which are advantageous in terms of processing costs, have also attracted great attention. [6,7] Like common dopant techniques, when a specific amount of a polymorph with a lower energy emission is embedded into a host polymorph with higher energy emission, the mixed polymorph solid can show mixed luminescence from a homogeneous solid form, modulating the color of luminescence in solid materials (Figure 1). Although this concept of "polymorphic doping" would give a system with simpler composition than those of common multi-chromophoric systems, it has never been achieved in practice.…”
