在本文中，我们报告了球形和立方硫化铜空心结构的合成，以及形状和厚度对合成产物的光热转换的影响。以球形和立方相Cu 2 O为模板，采用牺牲模板法合成了不同厚度的硫化铜空心结构。用紫外-可见光谱仪研究了合成产物的光吸收特性。利用自制的AUT-FSL半导体/固体激光器评价系统研究了其光热转换性能。结果表明，所制备的产物在可见光区具有明显的吸收。在波长为635 nm、功率为0.015 W的激光束照射下，在60 s内，球形和立方体硫化铜空心结构质量分数为0.24%的水悬浮液的温升分别为5 ℃和6 ℃。相反，在相同条件下，水的温度几乎没有升高。
In the current paper, we report the synthesis of spherical and cubic copper sulfide hollow structures, as well as the influence of shape and thickness on the photo-thermal conversion of the as-synthesized products. Copper sulfide hollow structures of different thickness were synthesized base on a sacrificial template strategy using spherical and cubic Cu2O precursors as templates. Optical absorption of the as-synthesized products was investigated with UV-Vis spectrometer. Photo-thermal conversion property was studied with a lab-made evaluation system equipped with an AUT-FSL semiconductor/solid state laser. The results indicate that the as-prepared products exhibited significant absorption in visible light regions. Under the irradiation of laser beam with a wavelength at 635 nm and a power of 0.015 W, the temperature elevations of the aqueous suspensions containing 0.24% mass fraction of spherical and cubic copper sulfide hollow structures were measured to be 5 °C and 6 °C within 60 seconds, respectively. On the contrast, water showed little temperature elevation under the same conditions.
