采用简单的溶剂热法制备了不同形状的k0.3 wo3蓝颜料。采用x射线衍射、x射线光电子能谱、扫描电镜、透射电镜和分光光度计对合成的k0.3 wo3颜料进行了表征。发现wcl6的浓度对k0.3 wo3颜料的形貌有很大的影响。随着wcl6浓度的增加，可以得到由纳米棒组成的纺锤状k0.3 wo3、由纳米棒组成的微球结构和由纳米片组成的微花结构。得到的纺锤形k0.3 wo3比k0.3 wo3微球和微花具有更高的近红外屏蔽能力。这可能是由于较高的长径比和较高的自由载流子浓度引起了K0.3WO3局部表面等离子体共振吸收的增强。用k0.3 wo3镀膜玻璃覆盖的加热箱内部温度降低了约8.5 °C。因此，合成的具有高可见光透明度和高近红外屏蔽能力的k0.3 wo3蓝色颜料具有应用于智能窗户涂层的潜力，以减少热量的积聚。
Different shaped K0.3WO3blue pigments were prepared by a simple solvothermal method. The as-synthesized K0.3WO3pigments were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, transmission electron microscopy, and spectrophotometer. It's found that the concentration of WCl6had a great influence on the morphology of K0.3WO3pigments. Spindlelike K0.3WO3composed of nanorods, microsphere structures composed of nanorods and microflower structures composed of nanosheets could be obtained with an increasing WCl6concentration. The obtained spindle shaped K0.3WO3showed higher near infrared shielding ability than that of K0.3WO3microspheres and microflowers. The reason could be attributed to the enhanced local surface plasmon resonance absorption induced by higher aspect ratio and higher free carrier concentrations of spindleliked K0.3WO3. An approximately 8.5 °C decrease in inner temperature was obtained for the heat box covered with K0.3WO3coated glass. Therefore, the synthesized K0.3WO3blue pigments with high visible light transparency and high near infrared shielding ability have the potential to be applied in smart window coatings to reduce the heat build-up.
