【摘要】 通过共沉淀法合成了尖晶石结构Cu_1-xZn_xBi₂O₄（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。更多还原

【Abstract】 Spinel structure Cu_1-xZn_xBi₂O₄（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.更多还原
