Aeromaterials are a new class of highly porous materials that attract increasing interest due to their potential applications in electronics, sensorics, microfluidics, etc. In this work, we report on fabrication of aero-ZnS by using two technological approaches: hydride vapor phase epitaxy (HVPE) and physical vapor transport (PVT) on sacrificial templates consisting of networks of ZnO interconnected microtetrapods. The aero-ZnS fabrication based on HVPE resides in growth of CdS on sacrificial micro-tetrapods of ZnO with subsequent transformation of CdS into ZnS and removal of the sacrificial ZnO core. For the aero-ZnS fabrication by PVT, the Sn2S3 crystals and networks of ZnO microtetrapods were used as precursors. The morphology of the produced material was investigated by SEM, while its crystalline and optical quality is assessed by X-ray diffraction analysis and PL spectroscopy, respectively.
