Abstract

TbGa₃(BO₃)₄ crystals were grown using the Bi₂Mo₃O₁₂:B₂O₃:Tb₂O₃ flux, which decreases contamination of Bi in the resulting crystal. The produced compound crystallizes in the R32 space group with unit cell parameters: a = 9.4512(4) Å, c = 7.4532(2) Å. A strong green emission of the luminescence is primarily dominated by the ⁵D₄ to ⁷F₅ transition in Tb³⁺. Annealing these crystals in a hydrogen atmosphere at 800 °C causes a reduction in the luminescence efficiency. On the other hand, annealing in air results in the increment of QY up to the value of 38%.

TbGa3(BO3)4 晶体的晶体生长和发光特性

摘要利用Bi2Mo3O12:B2O3:Tb2O3通量生长出了TbGa3(BO3)4晶体，从而减少了晶体中的铋污染。所生成的化合物在 R32 空间群中结晶，其单胞参数为：a = 9.4512(4) Å，c = 7.4532(2) Å。在 800 °C 的氢气环境中退火会降低这些晶体的发光效率。另一方面，在空气中退火会使 QY 值增加到 38%。
