标题：urchin-shaped bi2s3/cu2s/cu3bis3 composites with enhanced photothermal and ct imaging performance

abstact：urchin-shaped bi2s3/cu2s/cu3bis3 nanocomposites were successfully prepared in this study through one-pot synthesis, which involved microwave-assisted simultaneous pyrolysis of two precursors. the as-prepared bi2s3/cu2s/cu3bis3 hybrids exhibit stronger absorption in the near-infrared regime than the individual components, i.e., bi2s3, cu2s, and cu3bis3. the photothermal conversion efficiency (η) of bi2s3/cu2s/cu3bis3 composites can even reach 43.8%, which is significantly higher than that seen with most of the transition metal chalcogenide materials. the excellent photothermal performance of bi2s3/cu2s/cu3bis3 hybrids is likely arising from its unique urchin-like structure, in which needle-like bi2s3/cu2s nanocomposites grow from the core of cu3bis3. the copresence of bi2s3 and cu2s also leads this newly synthesized composite to produce high contrast for x-ray computer tomography imaging, an important property required for a great potential application in theranostic cancer treatment.
