A facile synthesis and photoluminescence of porous S-doped ZnO architectures

A facile process is demonstrated to synthesize porous S-doped ZnO architectures. The products were characterized by X-ray diffraction (XRD), Raman spectrum, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and photoluminescence (PL) spectra, respectively. The results indicate that the porous structured products are composed of many pores and wormlike nanoparticles with sizes ranging from 100 to 300 nm, exhibiting a strong green emission and a relatively weak ultraviolet emission. The correlation between structure and photoluminescence is also discussed.
