synthesized PILs. These metal oxides were prepared by sol-gel method and doped over the synthesized ILs by making thin films by spin coating method. The focus of the present study is to learn how the band gap of p-type and n-type metal oxide varies when it is incorporated over the PILs. Their structure, optical properties and morphology were studied through FT-IR, UV-Visible, photoluminescence and XRD spectral
本文报道了通过微波辐射法通过简单的质子转移反应制备两种质子离子液体(PIL)乳酸2-甲基咪唑鎓盐和乙酸2-甲基咪唑鎓盐。这项工作进一步改善了诸如CuO(p型),ZnO(n型)[两种过渡金属氧化物]和SnO 2(n型非过渡金属氧化物)之类的半导体金属氧化物对合成PIL的影响。这些金属氧化物通过溶胶-凝胶法制备,并通过旋涂法制备薄膜而掺杂在合成的IL上。本研究的重点是了解在PIL上掺入p型和n型金属氧化物的带隙如何变化。通过FT-IR,UV-Visible,光致发光和XRD光谱研究了它们的结构,光学性质和形态。
