Abstract :
The hydrothermal synthesis and optical properties of Nb5+-doped lithium metasilicate and lithium disilicate
nanomaterials were investigated. The microstructures and morphologies of the synthesized Li2 −2xNb2xSiO3 + δ and
Li2 −2xNb2xSi2O5 + 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 Li2SiO3 (space group Cmc21) and Li2Si2O5 (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.
