Synthesis of CdxZn1−xS Nanoparticles in Porous Vycol Glass by Reaction of Single-source Precursors

Abstract

CdxZn1−xS nanoparticles incorporated in a nanoporous Vycor glass (PVG) were fabricated by incorporating and decomposing bis(N,N-diethyldithiocarbamato)cadmium and bis(N,N-dibutyldithiocarbamato)zinc sequentially. Fabrication of the alloy compound was confirmed by the shift in the X-ray diffraction pattern with respect to those of pure CdS and ZnS.

Microwave Synthesis of ZnxCd1−xS Nanorods and Their Photocatalytic Activity under Visible Light

“…Zn x Cd 1-x S nanocrystals, which belong to the binary II-VI nanocrystals, have been widely used as optoelectronic devices and biomedical tags due to their novel size-tunable properties. [12][13][14][15][16][17][18][19][20][21] Through changing the compositions, band gap energy and band positions that can drive both oxidation and reduction under visible light irradiation can be formed. Some researchers have investigated the synthesis of high-quality Zn x Cd 1-x S nanocrystals with high photoluminescence properties.…”

Hydrothermal synthesis and growth mechanism of ZnxCd1−xS nanoflake dendrites

“…2b). It is well known that the separated nucleation of ZnS and CdS will result in peaks summation of ZnS and CdS in XRD patterns [5]. Fig.…”

“…It is well known that when introducing CdS (E g = 2.38 eV) into ZnS (E g = 3.67 eV), these compounds can form a series of Zn x Cd 1−x S solid solution, of which the band gap can be continuously tunable and cover the visible range from green to the ultraviolet [4][5][6][7][8][9], resulting in highly narrow luminescence and can be synthesized in multiform matrices. Therefore, the method of solid solution may be a promising solution for the present problems of wavelength tuning of II-VI semiconductor nanomaterials.…”

“…Especially, the morphologies of present Zn x Cd 1−x S nanomaterials are comparatively simple and crude (no more than nanocrystals [11], nanoparticles [5], nanorods [7], nanoribbons [9], etc.). To our best knowledge, few works have been performed on the shapetuning and relevant growth mechanism of hydrothermal fabricated Zn x Cd 1−x S ternary alloys.…”

Application of content optimized ZnS-ZnO-CuS-CdS heterostructured photocatalyst for solar water splitting and organic dye decomposition

“…There are two promising approaches for improving both light absorption and utilization of electron-hole pairs. The first is to develop new materials such as doped compounds to improve visible light absorption and electron/hole mobility, as reported other studies (Cd 1−x Zn x S [1,2] and Zn 1−x Cu x [3]). The second is to use heterostructure having multi-components playing separate roles for absorbing photons and consuming electron-hole pairs, for example, TiO 2 -CdS [4,5], and ZnS-CuS-CdS [6].…”
