Flux Growth, Thermal Stability, and Luminescence Properties of RAl2.07(B4O10)O0.6 (R = La–Nd) Crystals
In this paper, we report growth of RAl2.07(B4O10)O0.6 (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)LaAl2.07(B4O10)O0.6 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.
期刊介绍:
Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
