Synthesis and analysis of CuS with different morphologies using cyclic microwave irradiation

Nano- and micro-sized CuS crystals were successfully synthesized from copper and sulfur sources (CuCl2 . 2H2O, CuBr, Cu(CH3COO)2 . H2O, CH3CSNH2, NH2CSNHNH2 and NH2CSNH2) in ethylene glycol assisted by the cyclic irradiation of different microwave powers and prolonged times. By using XRD and SAED, CuS (hcp) was detected. The products characterized using SEM and TEM compose of assemblies of nano-flakes, clusters of nano-particles, nano-fibers, nano-rods and sponge-like structures influenced by the synthesized conditions. Their lattice vibrations are in the same Raman wavenumber at 474 cm−1. Among the different products, the emission peaks are over the range 414–435 nm (2.85–2.99 ev). Reaction evidences of the sources were provided using FTIR. Phase and morphology formations are also proposed on according to the analytical results.
