Abstract
- δ-BiB3O6 shows a comparable nonlinear optical performance with the famous α-BiB3O6. It can be prepared either by a high temperature-high pressure method or by a sol–gel method associated with RE3+-doping (RE = La, Ce, Pr, and Nd). A direct solid state reaction at 700 °C stabilized 20 atom% La3+ doped δ-BiB3O6 compared to the previously reported record (15 atom%) in the literature. La3+ doping would not only expand the thermodynamically stable region, which is critical for the synthesis, but also hasten the crystallization process. Moreover, Eu3+, a smaller RE cation, was also doped for the first time at a high doping level (7 atom%) simply by a seed-assisted solid state reaction, which apparently provides additional functionality and will prompt further efforts on single crystal growth of RE3+-doped δ-BiB3O6 under ambient pressure. The combined powder X-ray diffraction and transmission electron microscopy analysis underpinned the phase purity and doping homogeneity of cation doped bismuth borates. UV-excited red luminescence was observed for δ-Bi0.93Eu0.07B3O6. [ABSTRACT FROM AUTHOR]
