Synthesis, Growth, and Luminescence Properties of Rare Earth Borates KSrY(BO3)2: Tb3+ and Tb4+
KSrY(BO3)2: Tb3+ and Tb4+ solid solutions have been obtained using the solid-state synthesis and top-seeded solution growth method from the KF flux. Comparing the two types of Tb spectra 3d3/2 TbO2 (Tb4+) and Na3Tb(BO3)2 (Tb3+) with annealing in air of the KSrTb(BO3)2 crystal, X-ray photoelectron spectroscopy (XPS) revealed that the crystal contains about 15% of Tb4+. The entire Y/Tb series has polymorphic phase transitions that occur at temperatures between 550 and 600 °C. Synthesis and subsequent treatment methodology have an impact on the resulting Tb3+/Tb4+ ratio in the sample. The best luminescent properties were measured on the composition KSrY0.9Tb0.1(BO3)2, which was annealed at 700 °C under a hydrogen flow and cooled slowly.
期刊介绍：
The aim of Crystal Growth & Design is to stimulate crossfertilization of knowledge among scientists and engineers working in the fields of crystal growth, crystal engineering, and the industrial application of crystalline materials.
Crystal Growth & Design publishes theoretical and experimental studies of the physical, chemical, and biological phenomena and processes related to the design, growth, and application of crystalline materials. Synergistic approaches originating from different disciplines and technologies and integrating the fields of crystal growth, crystal engineering, intermolecular interactions, and industrial application are encouraged.
