摘　　要：通过共沉淀法合成了尖晶石结构Cu_(1-x)Zn_(x)Bi_(2)O_(4)(x=0, 0.1, 0.3, 0.5, 0.7)可逆热致变色无机材料,并通过X射线衍射(XRD)、红外光谱(IR)、紫外可见近红外吸收光谱(UV-vis-NIR)、扫描电镜(SEM)等对其结构和热致变色性质进行了研究。通过X射线衍射数据以及振动光谱技术,分析了不同掺杂成分相纯度和结构的演变。样品的颜色在室温状态下显示出从深褐色到淡黄色的转变,具有应用于变色测温的潜力。Spinel structure Cu_(1-x)Zn_(x)Bi_(2)O_(4)(x=0,0.1,0.3,0.5,0.7)were synthesized by co-precipitation method,which show reversible thermochromic property.It’s structure and properties were studied by X-ray diffraction(XRD),Fourier transform infrared spectroscopy(FT-IR),ultraviolet-visible-near-infrared spectroscopy(UV-vis-NIR),and scanning electron microscopy(SEM).The phase purity and structure evolution of different doping components were analyzed by X-ray diffraction data and vibration spectroscopy.The color of samples shows a change from dark brown to light yellow at room temperature,with potential applications in measuring temperature via color change.
