Structural and optical properties of ZnS/niobate composites synthesized by exfoliation/self-assembly processing

Structure and optical property of CdS/niobate composite synthesized by exfoliation/self-assembly processing

“…Another case is that the CdS particles embedded in the niobate with other modes may be in disorder, also not detected by XRD. Similar studies on the ZnS/niobate and ZnO/niobate composites were carried out in our recent works [22,23].…”

Synthesis and optical properties of composites based on ZnS nanoparticles embedded in layered magadiite

“…These results suggest that the photoluminsecence properties of ZnS nanoparticles incorporated into magadiite may be modified by the host magadiite. Previous studies on the ZnS nanoparticles incorporated in inorganic or organic host materials have reported that ZnS nanoparticles ZnS nanoparticles in layered magadiite incorporated in different inorganic or organic host materials have different photoluminescence properties (Ni et al, 2005;Ullah et al, 2008;Chen et al, 2010;Khaorapapong et al, 2010;Pan et al, 2012;Ummartyotin et al, 2012). The PL spectra of ZnS-Mag-2 are similar to that of pure ZnS, probably because some ZnS particles, which have not been incorporated into the interlayer space of magadiite, may have a larger size and thus exhibit similar photoluminescence as the pure ZnS.…”

“…Zhang et al, 2003;Sayle et al, 2006;Kozak et al, 2010;Song et al, 2013). The ZnS nanoparticles exhibit different photoluminescent properties when combined with different organic molecules or incorporated into different inorganic materials or polymers (Ni et al, 2005;Ullah et al, 2008;Chen et al, 2010;Khaorapapong et al, 2010;Ummartyotin et al, 2012;Pan et al, 2012).…”

Highly Efficient Liquid-Phase Exfoliation of Layered Perovskite-like Titanates HLnTiO4 and H2Ln2Ti3O10 (Ln = La, Nd) into Nanosheets

“…Being nanoscale objects, perovskite nanosheets have large specific surface areas and small sizes that provide an enhanced number of active sites, efficient reactant adsorption and reduced intensity of charge carrier recombination [62], which, in turn, explains their improved photocatalytic activity in comparison with that of their bulk counterparts. Moreover, perovskite nanosheets may be used as building blocks to obtain new layered materials via controllable self-assembly [63][64][65][66]. Since exfoliation and assembly processes are usually performed via soft chemistry techniques, final materials preserve crystal structure and, consequently, valuable properties of initial compounds.…”
