“…When the second hydrothermal time was increased to 2 h, polycrystalline CdS rods transformed into pyramidal and frustum-like rods ( Figure 2B). This transformation was also found by Li's group when the reaction time was increased above 1 h (Yang et al, 2013). Upon further increasing the reaction time to 3 h, an obvious nanostep structure was formed on the surface of the CdS rods.…”

CdS nanostep-structured arrays were grown on F-doped tin oxide-coated glasses using a two-step hydrothermal method. The CdS arrays consisted of a straight rod acting as backbone and a nanostep-structured morphology on the surface. The morphology of the samples can be tuned by varying the reaction parameters. The phase purity, morphology, and structure of the CdS nanostep-structured arrays were characterized by X-ray diffraction and field emission scanning electron microscopy. The light and photoelectrochemical properties of the samples were estimated by a UV-Vis absorption spectrum and photoelectrochemical cells. The experimental results confirmed that the special nanostep structure is crucial for the remarkable enhancement of the photoelectrochemical performance. Compared with CdS rod arrays, the CdS nanostep-structured arrays showed increased absorption ability and dramatically improved photocurrent and energy conversion efficiency. This work may provide a new approach for improving the properties of photoelectrodes in the future.

“…The schematic fabrication process of the MIS LEDs is illustrated in Figure a. A CdS NR array was firstly grown on a pre‐cleaned fluorine‐doped tin oxide (FTO) glass substrate via a hydrothermal process (see details in the Experimental Section). Subsequently, a SiO 2 thin film was deposited via PECVD as the shell to cover the CdS NRs.…”

“…The CdS nanorod array was prepared on fluorine‐doped tin oxide (FTO) glass by a hydrothermal process as described previously . First, a nutrient solution of 15 m m was obtained by mixing thiourea, cadmium nitrate, and reduced glutathione at a molar ratio of 1:1:0.6 in deionized water, which was then put into a stainless steel autoclave.…”

Enormous advancement has been achieved in the field of one-dimensional (1D) semiconductor light-emitting devices (LEDs), however, LEDs based on 1D CdS nanostructures have been rarely reported. The fabrication of CdS@SiO core-shell nanorod array LEDs based on a Au-SiO -CdS metal-insulator-semiconductor (MIS) structure is presented. The MIS LEDs exhibit strong yellow emission with a low threshold voltage of 2.7 V. Electroluminescence with a broad emission ranging from 450 nm to 800 nm and a shoulder peak at 700 nm is observed, which is related to the defects and surface states of the CdS nanorods. The influence of the SiO shell thickness on the electroluminescence intensity is systematically investigated. The devices have a high light-emitting spatial resolution of 1.5 μm and maintain an excellent emission property even after shelving at room temperature for at least three months. Moreover, the fabrication process is simple and cost effective and the MIS device could be fabricated on a flexible substrate, which holds great potential for application as a flexible light source. This prototype is expected to open up a new route towards the development of large-scale light-emitting devices with excellent attributes, such as high resolution, low cost, and good stability.

“…Fabrication of photovoltaic devices : Prior to the growth of CdS nanorods, a dense TiO 2 layer was first deposited on a cleaned FTO glass substrate by dip‐coating with a TiO 2 organic solution (made by using a titanium butoxide/diethanolamine/absolute ethanol solution), followed by a sintering at 500 °C for 30 min. CdS nanorod arrays on TiO 2 ‐coated FTO were then prepared by using a literature method with incorporated modifications 22. Briefly, 0.05 M Cd(NO 3 ) 2 (20 mL), 0.05 M thiourea solution (20 mL), and 0.03 M glutathione solution (20 mL) were mixed and loaded into a 100 mL autoclave containing a piece of TiO 2 ‐coated FTO substrate.…”

“…Consequently, photovoltaic devices were fabricated in the configuration of a FTO/TiO 2 compact layer (c‐TiO 2 )/CdS nanorods (NRs)/Ag 8 GeS 6 NCs/Spiro‐MeTAD/Au, and the relative band positions of the materials employed in the devices is given in Figure 4 b. The CdS NRs prepared on FTO coated with a compact layer of TiO 2 , by a hydrothermal approach,22 were employed as the n‐type electron transporter, and the Ag 8 GeS 6 NCs, as the light harvester, were deposited onto them by spin coating of a nanocrystal solution by using a layer‐by‐layer approach. A Spiro‐MeOTAD interfacial layer was then deposited onto them because it favors hole extraction and eases the formation of the ohmic contact for the back electrode, resulting in a relatively high device performance for solar cells 23.…”

A facile colloidal approach to synthesize Ag8 (Ge1-x ,Snx )(S6-y ,Sey ) nanocrystals (NCs) in a highly controlled way across the entire compositional ranges (0≤x≤1, 0≤y≤6) has been developed. The NCs exhibit a uniform size distribution, highly crystalline structure, over 1 g scalable synthesis, and tunable band gaps in the range of 0.88-1.45 eV by varying their chemical compositions. The Ag8 GeS6 NCs with a band gap of approximately 1.45 eV were employed as a model light harvester to assess their applicability in solar cells by a full solution-processing device, yielding an efficiency of 0.28 % under AM1.5 illumination, demonstrating their application potential in solar energy utilization.
