Use of recrystallized Y3Fe5O12 seeds for growing yttrium iron garnets from flux

The paper deals with segregation of rare earth doping cations in solid-state hosts. Increased concentration of Ce3+ and Nd3+ on the grain boundaries of transparent garnet optical ceramics was recently reported. These experimental results correlate well with low segregation coefficients of Ce3+ and Nd3+ large rare earth cations and the higher segregation coefficients for small rare earth cations like Yb3+ in the garnet structure observed in the melt crystal growth and thin film liquid phase epitaxy from flux. Thus, the segregation in solid-state grain growth is qualitatively similar to that observed in the melt/flux growth of the garnet single crystals. The data on segregation in the melt/flux crystal growth are widely available and can be used for preliminary estimation of the dopant distribution in the ceramics produced from the solid state. This information could help to predict distribution of doping cations in the solid state hosts that is important in development of uniform and highly efficient optical materials.

“…Therefore, the solubility of transported materials can be several tenths of a percent, in contrast to the classical method, in which the amount of crystallized material is no less than 6-8% of the total amount of liquid phase [2]. Since the material is transported from the hot end to the cold end only as a result Lowering the synthesis temperature makes it possible not only to grow crystals of higher quality but also obtain materials that are thermodynamically unstable at high temperatures.…”

The possibilities of growing crystals of metals, alloys, chalcogenides, and pnictides in halide melts using a steady-state temperature gradient are analyzed. Halides of alkali metals and aluminum can be used as transport media. The choice is determined by the melting temperature of salt mixtures. A conducting contour can also be applied to increase transport efficiency. This technique of crystal growth is similar to the electrochemical method. To eliminate interference during migration, some elements can be isolated and forced to migrate through independent channels to the crystal formation region. The technique considered here makes it possible to grow crystals of necessary quality without special equipment; the small crystal sizes are sufficient for laboratory study.

Due to their physical properties and potential applications in energy conversion and storage, transition metal dichalcogenides (TMDs) have garnered substantial interest in recent years. Amongst this class of materials, TMDs based on molybdenum, tungsten, sulfur and selenium are particularly attractive due to their semiconducting properties and the availability of bottom-up synthesis techniques. Here we report a method which yields high quality crystals of transition metal diselenide and ditelluride compounds (
