Abstract

Abstract The hydrothermal synthesis and optical properties of Nb 5+ -doped lithium metasilicate and lithium disilicate nanomaterials were investigated. The microstructures and morphologies of the synthesized Li 2 -2 x Nb 2 x SiO 3 + δ and Li 2 -2 x Nb 2 x Si 2 O 5 + δ nanomaterials were studied by powder X-ray diffraction and scanning electron microscopy techniques, respectively. The synthesized niobium-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 photoluminescence spectra of the synthesized materials are studied. The measured optical properties show dependence of the dopant amounts in the structure.
