A facile route to synthesize three-dimensional CdS nanocrystals

Synthesis of nanoscale inorganic crystals with controlled size, shape, and hierarchy has attracted intensive research interest, since they are potential building blocks for advanced materials and optoelectronic devices. As an important group II-IV semiconductor with extensive applications in optical and electronic nanodevices, complex three-dimensional nanocrystals CdS with well-defined structures have just received great attentions since they offer new opportunities as building blocks to fabricate or assemble into advanced materials for further generation of optoelectronic devices, we report for the first time to large-scale synthesize an interesting 3D structured CdS nanocrystals by a facile hydrothermal method. The photoluminescence results of the 3D CdS nanocrystal indicated they have the potential applications for the building blocks on optoelectronic devices.
