Abstract This paper reports comparative analysis on the optical properties of W1−XMoxO3⋅0.33H2O (X = 0, 25, 50, 75 and 100%) semiconductor oxides synthesized by hydrothermal and microwave radiation techniques. Research from the utilized optical techniques revealed that the result of smaller values of 1.90 eV energy band gap and optical properties of the solid solutions at the visible region of the light spectrum favored hydrothermal synthetic route compared to microwave radiation. Crystallographic analysis via XRD patterns was carried out to certify the purity of the solid solutions synthesize by the two methods. DFT + U was used to study the electronic structure of the compounds with x = 0 to x = 75% Mo.

摘要 本文报道了通过水热和微波辐射技术合成的 W1−XMoxO3⋅0.33H2O (X = 0, 25, 50, 75 和 100%) 半导体氧化物的光学性质的比较分析。所用光学技术的研究表明，与微波辐射相比，1.90 eV 能带隙的较小值和固溶体在光谱可见区的光学性质有利于水热合成路线。通过XRD图谱进行晶体分析以证明两种方法合成的固溶体的纯度。DFT + U 用于研究 x = 0 至 x = 75% Mo 的化合物的电子结构。
