In this paper, we reported the synthesis of a new family of thermal stable Mn-doped DyInO₃ blue pigment materials. All of the samples were synthesized by a conventional solid state method. Powder x-ray diffraction refinement results showed that the structures of the as-prepared materials were hexagonal (space group: P6₃cm), and their cell parameters decreased with Mn content improving. Scanning electron microscopy (SEM) showed that the particle size can be directly used for coating. Infrared (IR) and Raman spectra show the presence of random disorder and structural modifications without phase transition. Diffuse reflection spectra were obtained over the range of wavelength 200–2500 nm indicated the blue color is caused by the allowed DMSO-d6 transition. All the samples show excellent near-infrared reflectance which means lower heat build-up. Temperature-dependent color and UV-vis spectra indicated that a continuous structural evolution accompanied by the allowed DMSO-d6 transition. Thus, this paper provides a family of new thermal stable blue pigment for potential applications.

在本文中，我们报道了一种新型的热稳定锰掺杂的DyInO ₃蓝色颜料材料的合成。所有样品均通过常规固态方法合成。粉末X射线衍射细化结果表明，所制备材料的结构为六角形（空间群：P 6 ₃ cm），并且随着Mn含量的提高，它们的晶胞参数降低。扫描电子显微镜（SEM）表明，该粒径可直接用于涂层。红外（IR）和拉曼光谱显示存在随机无序和结构修饰，没有相变。在200-2500 nm波长范围内获得了漫反射光谱，表明蓝色是由允许的DMSO-d6跃迁引起的。所有样品均显示出优异的近红外反射率，这意味着较低的热量积聚。温度相关的颜色和紫外可见光谱表明，连续的结构演变伴随着允许的DMSO-d6转变。因此，本文为潜在的应用提供了一系列新的热稳定的蓝色颜料。
