- Аннотация: Single crystals of undoped and Ce3+, Tb3+, and Eu3+/Tb3+/Ce3+ co-doped Ba12(BO3)6[BO3][LiF4] crystals were grown from high-temperature solutions. The Ba12(BO3)6[BO3][LiF4] compound crystallizes in the structural type of barium orthoborate Ba3(BO3)2 with porous Ba12(BO3)66+ cationic framework filled with disordered anionic groups. The PL and PLE spectra of undoped and rare-earth-doped crystals were studied. The photoluminescence temperature dependences in the range of 77–300 K were recorded. The shape and position of lines in the spectra are typical of cerium, terbium, and europium ions. Luminescence lifetime constants were measured in the range of 77–300 К. It was shown that at the excitation wavelength of 300 nm and 370 nm at 300 K, Ba12(BO3)6[BO3][LiF4]:Eu3+, Tb3+, Ce3+ crystals have luminescence close to daylight with CIE chromaticity coordinates and correlated color temperature of (0.335; 0.309), 5352 K and (0.295; 0.362), 7121 K, respectively. Our results indicate that rare-earth-doped Ba12(BO3)6[BO3][LiF4] crystals can besidered a candidate for the conversion of LED emission into white light.
