2013年4月1日 · Spherical ZnS based nanoparticles (hierarchical architectures) were successfully synthesized using Zinc bis(salicyle aldehitato), Zn(Sal) 2, thioacetamide (TAA) and thioglycolic acid (TGA) as Zn 2+, sulfur source and capping agent, respectively.

SEM micrographs show almost uniform dispersion of the ZnS and CdS nanoparticles in the respective polymers. The TGA reveals that the ZnS/PVA and CdS/PVA thermal stability are most enhanced by the incorporation of the metal sulfide in the matrices of the polymers.

In this work, we prepared sulfur-zinc nanoparticles (ZnS-TGA) functionalized with thioglycolic acid by a hydrothermal method and tested their photodegradation ability by solar irradiation. ZnS-TGA were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), high-resolution transmission electron microscope (HR ...

2022年3月1日 · Bare and TGA-covered ZnS nanoparticles with spherical shapes, FCC structures ranging from 4 to 6 nm were generated directly in an aqueous phase by a reflux method. EDX studies confirmed the presence of zinc and sulfur as the only elements in …

2022年1月6日 · Ultraviolet-visible spectroscopy (UV–vis) and x-ray diffraction (XRD) confirmed the formation of the ZnS nanostructures. Thermal Gravimetric Analysis (TGA) and Brunner Emmet Teller (BET) confirmed the material was thermally stable up until 480 °C and mesoporous in nature, respectively.

2020年4月1日 · Ag 2 S/ZnS/TGA QDs IR 发光强度的增加伴随着平均发光寿命从 2.9 ns 增加到 14.3 ns，这被解释为 ZnS 形成过程中表面陷阱态的“愈合”壳。 首次，在Ag 2 S/ZnS/TGA核/壳QDs的形成过程中发现了发光强度光降解（以下简称疲劳）的增强。

2013年6月1日 · Zinc sulphide (ZnS) nanoparticles have been synthesized by the mechanochemical route. The prepared nanoparticles have been analyzed by X-ray diffraction (XRD), Field emission scanning electron microscope (FESEM), Energy-dispersive analysis of X-rays (EDAX), Ultraviolet–visible–near infrared (UV–Vis–NIR) spectrophotometer and ...

2022年7月7日 · ZnS quantum dots (ZnS QDs) are prepared in the absence and presence of thioglycolic acid (TGA) molecules by using a chemical precipitation method. The as-prepared ZnS QDs are characterized by photoluminescence (PL), UV–vis absorption, Fourier transform infrared (FTIR), and X-ray powder diffraction (XRD).

In the present work zinc sulfide (ZnS) nanoparticles (NPs) were synthesized on silicon wafer by femtosecond pulsed ablation processing of ZnS bulk target using an electrostatic field in argon...

2024年4月20日 · In the present work, we have developed a rapid, cost-effective aqueous phase route to synthesize water-soluble Thioglycolic acid (TGA) capped CdSe/ZnS (CdSe/ZnS + TGA) QD sensor. Synthesized QD sensor has been successfully validated its candidature for the efficient detection of hazardous heavy metal ions (Xn+) specifically chromium (Cr3+) and ...
