“…Lithium metasilicate has been the topic of several studies because of their potential application as tritium breeder material into the fusion reactors [97,98] as an ionic conductor [99,100] and as a candidate for luminescent materials [101,102]. In general, Li 2 SiO 3 has been synthesized by the conventional solid-state reaction method, and only some chemical routes have been studied such as the sol-gel, microemulsion and combustion methods [103][104][105].…”

Abstract:The present article aims to give a brief overview about the advantages of the hydrothermal crystallization method for the synthesis of advanced ceramics. Emphasis is given, not only on the conventional hydrothermal crystallization, but also on some of its variants; such as ultrasound-assisted, electrochemical-assisted, microwave-assisted and surfactant-assisted hydrothermal methods which open up new opportunities for the synthesis of ceramic materials with novel properties demanded for advanced applications. In the current work the synthesis of barium titanate (BaTiO 3 ), lithium metasilicate (Li 2 SiO 3 ) and sodium-potassium niobate (Na, K)NbO 3 powders are reported as cases of study.

The hydrothermal synthesis and optical properties of undoped and Sb 3+ -doped lithium metasilicate and lithium disilicate nanomaterials were investigated. The microstructures and morphologies of the synthesized Li 2−2x Sb 2x SiO 3 and Li 2−2x Sb 2x Si 2 O 5 nanoparticles were studied with powder X-ray diffraction and scanning electron microscopy techniques, respectively. The synthesized undoped and doped lithium metasilicate and lithium disilicate nanomaterials, respectively, are isostructural with the standard bulk Li 2 SiO 3 (space group Cmc2 1 ) and Li 2 Si 2 O 5 (space group Ccc2) materials. The electronic absorption and photoluminescence spectra of the synthesized materials are studied. The measured optical properties show dependence on the dopant amounts in the structure.

“…Among these phosphors, Ce 3+ -doped yttrium aluminum garnet (YAG), which emits yellow light, has found wide use as a phosphor for white light-emitting diodes (LED). However, investigating the luminescent properties of Ce 3+ -doped compounds is of continued interest for the development of novel phosphors [1][2][3][4][5][6][7][8][9][10][11][12][13][14], particularly Ce 3+ -doped scintillators [1,2,9,14], as the allowed 5d-4f transition has a short lifetime and high quantum efficiency in the 10-40 nm range [1].…”

Transparent mica glass-ceramics were prepared by heating parent glasses that had been doped with 0.5-15 mol% CeO 2 . During the melting and heat treatment, Ce 4+ ions in the specimens were reduced to Ce 3+ ions, and one or both of these ion species were then replaced Li + ions in the interlayers of the separated mica crystals. However, scanning transmission electron microscope (STEM) and Z-contrast imaging revealed that the mica crystals did not contain the same amount of Ce. On excitation at 254 nm, the parent glasses and glass-ceramics emitted blue light, which originated from the 5d to 4f transition of the Ce 3+ ions. The emission of the glass-ceramic containing a smaller amount of Ce was attributed to the Ce 3+ ions in both the glass phase and the mica crystals, whereas that of the glass-ceramics containing a larger amount of Ce was caused mainly by Ce 3+ ions in the mica crystals. The dependence of the emission band of the parent glasses on the amount of Ce was a unique feature of the Ce-doped transparent mica glass-ceramics and was not observed in previous studies of Eu-doped parent glasses and mica glass-ceramics.
