摘要

采用固相反应法制备了纯六钛酸钠(Na2 Ti6 O13)和锰掺杂六钛酸钠(Na2 Ti6 O13)。纯样品和掺杂样品的x射线衍射图显示为单相和单斜结构。用扫描电镜研究了所有合成材料的形貌。记录了这些样品的吸收光谱，并用Tauc关系计算了能带隙。带隙范围为3.71eV ~ 4.05 eV。

Tailoring of Band Gap in Manganese doped Sodium Hexa-titanate

Pure and Manganese doped Sodium Hexa-titanate (Na2 Ti6 O13) were synthesized using solid state reaction method. X-ray diffraction pattern reveals single phase and exhibit monoclinic structure of pure and doped samples. Morphologies of all synthesized materials have been studied using SEM. Absorption spectra of these samples have also been recorded and the same have been used to calculate the energy band gap using Tauc relation. The band gap lies in the range 3.71eV to 4.05 eV.
