“…The pure ZnS, ZnS-GO, and ZnS/Graphene (directly producing ZnS nanoparticle on pure graphene) exhibit one narrow band in the range 427-452 nm, which is due to sulfur vacancies and interstitial sulfur lattice defects or zinc in ZnS [44,45]. This is in agreement with published work on ZnS particles [46][47][48]. In our study, the maximum of PL emission spectra of ZnS-Graphene sample (Fig.…”

“…This peak translates into a band gap of 2.33 eV. 11,30 The sharp peak that appears to be convoluted with the much broader signature around 540 nm is due to an instrumental effect and is present in all profiles originating from the PL equipment used for this analysis.…”

Growth of Ultralong ZnS/SiO₂ Core−Shell Nanowires by Volume and Surface Diffusion VLS Process

et al. 2008

Nanowires of up to 1 cm in length and approximately 30 nm in diameter were synthesized through a simple chemical vapor deposition process. Scanning electron microscopy (SEM) data showed that these nanowires were well-aligned and grew in the direction along the flow of the carrier gas. Through transmission electron microscopy (TEM) and X-ray diffraction (XRD) analysis, the nanowires were found to be composed of a single-crystalline ZnS core and amorphous SiO 2 shell. Gold catalyst particles were found at the tips of the nanowires and completely encased by a silica shell. Photoluminescence (PL) measurements were performed on nanowire samples in which the synthesis time was systematically varied to provide information regarding growth dynamics. After a systematic study on the structure, we propose that the core-shell nanowires were formed via a distinct volume and surface diffusion process occurring simultaneously for different chemical species in and on the gold catalyst particle.
