摘要

Abstract—

In this paper, we report growth of RAl_2.07(B₄O₁₀)O_0.6 (R = La–Nd) rare earth aluminum dimetaborate single crystals from a K₂Mo₃O₁₀-based fluxed melt. We have studied the composition and thermal properties of the crystals and luminescence spectra of Tb³⁺- and Eu³⁺-doped (Eu,Tb)LaAl_2.07(B₄O₁₀)O_0.6 solid solutions. The results demonstrate that such compounds have a tendency toward gradual decomposition in open systems at temperatures below their melting point. We have identified the mechanism of their decomposition as a function of the nature of the RE cation. The Tb³⁺-doped material exhibits luminescence with a peak emission wavelength of 541 nm, and the strongest Eu³⁺ luminescence peak is located at 613 nm.
