我们从土耳其获得了一种由罗丹明B(Rh-B)有机染料化合物和Unye膨润土(UB)粘土组成的低成本、丰富的纳米颜料材料。用扫描电子显微镜(SEM)、粒度分布、粉末X射线衍射(PXRD)、傅立叶变换红外光谱(FT-IR)和热分析技术对纳米粒子进行了表征。织构分析结果表明，Rh-B/UB纳米粒子的粒径分布(d：0.5-平均分布)约为100 nm。扫描电子显微镜照片显示，样品的粒径约为纳米级。X射线衍射和热分析表明，在2 0 0~5 0 0℃温度范围内，膨润土的层间距相差1.46°(2θ)，质量损失高7.80%。
We obtained a low cost and abundant nanopigment material composed of Rhodamine B (Rh-B) organic dye compound and Unye bentonite (UB) clay from Turkey. The characterization of the nanopigment was investigated using scanning electron microscopy (SEM), particle size distribution, powder X-ray diffraction (PXRD), Fourier transformed infra-red spectroscopy (FT-IR) and thermal analysis techniques. According to the result of texture analyses, we showed that the particle size distribution (d: 0.5-mean distribution) of Rh-B/UB nanopigment material was around 100 nm diameter. It was also demonstrated that the samples had a particle size around nm diameter in SEM images. As seen in the PXRD and thermal analysis, there is a difference in basal spacing by 1.46° (2θ) and a higher mass loss by 7.80% in the temperature range 200–500 °C compared to the raw bentonite.
