摘要
Zn3Ta2O8 has been synthesized by hydrothermal method using tantalum (V) oxide and zinc nitrate. The crystal structure and microstructure, phase composition and the absorption of Zn3Ta2O8 nanomaterials were characterized by X-ray diffraction, FT/IR measurements, UV-VIS measurements, PL measurements, SEM and AFM techniques and BET analysis. XRD results show the single phase of Zn3Ta2O8 and the average particle size that is 52 nm. This narrow nanometer size was also confirmed by AFM measurements. BET analysis revealed that the nanomaterials are mesoporous. The PL spectra show the blue luminescence of Ta2Zn3O8. Besides, in the present work we report ab initio calculations regarding electronic properties of Zn3Ta2O8; the theoretical results are compared with the experimental ones. (C) 2013 Elsevier B. V.
