  • 本研究利用固態高溫搭配助熔劑長晶法,成功合成出三種不同結構的新穎四元硫鹵族化合物,別為化合物1、化合物2及化合物3,此三個化合物具有結構上的關聯性。化合物1經UV-Vis-NIR光譜儀進行吸收測試,其能隙大約在0.67 eV,屬於一個窄能隙的半導體材料。化合物2經UV-Vis-NIR光譜儀進行吸收測試,其能隙大約在0.74 eV。化合物3經UV-Vis-NIR光譜儀進行吸收測試,其能隙大約在0.8 eV。

    Three chalcohalide compounds with different structures had been synthesized by high temperature solid state and flux-growth method 。
    The three compounds , which labeled as compound 1 to 3. These three compounds adopt 3-D frameworks,in which the building blocks are related to each other in an interesting manner. The compound 1 of UV-Vis and Near-IR absorption spectrum of the compound in the first system reveal a band gap of 0.67 eV。The compound 2 of UV-Vis and Near-IR absorption spectrum of the compound in the first system reveal a band gap of 0.74 eV。The compound 3 of UV-Vis and Near-IR absorption spectrum of the compound in the first system reveal a band gap of 0.8 eV。
