Size controlled synthesis of silver sulfide nanostructures by multi-solvent thermal decomposition method

2D Ductile Transition Metal Chalcogenides (TMCs): Novel High‐Performance Ag2S Nanosheets for Ultrafast Photonics

“…Large thermal and optical threshold damage. They have attracted wide interest in nanoelectronics and nanophotonics 5–8. In addition, 2D MoS 2 , as a member of 2D TMCs, is extensively used as saturable absorber (SA) to achieve outstanding ultrashort pulses in near infrared (NIR) to mid‐infrared bands due to its broadband saturated absorption, suitable adjustable bandgap and ultra‐fast relaxation time.…”

Photothermally Active Upconversion Core–Shell NaGdF4:Yb:Tm@Cu Nanostructures: Synthesis and Theranostic Properties

“…The NGF synthesis procedure was adapted from a previous report . Thermal decomposition was used to synthesize the NGF cores, leading to highly crystalline and stable particles.…”

“…Imaging techniques such as florescent imaging, magnetic resonance imaging (MRI), radiolabeling techniques, and thermal imaging are currently widely used . However, new probes with the ability to reach small targets are under development . Research has been focusing on small probes that can recognize and specifically target cancer cells .…”

“…Compared with other methods such as hydrothermal, sol–gel, and hydrogel methods; thermal decomposition and hot injection methods provide better homogeneous nanoparticle size control for small nanoparticle synthesis. The thermal decomposition method has been shown to produce small nanoparticle sizes for various kinds of nanoparticles including NaGdF 4 and other metallic nanoparticles . Hot injection in the absence of air can avoid the formation of contaminants, such as GdO x and CuO, which lead to polydispersity in particle size .…”

Green synthesis, characterization of silver sulfide nanoparticles and antibacterial activity evaluation

“…Silver sulfide (Ag2S) nanomaterial is an important material used in solar cell batteries, thermoelectric sensors, infrared detectors, photovoltaic cells, conductors and antimicrobial activity (Bruhwiler et al, 2002;Fakhri et al, 2015;Kumari et al, 2014). Several methods have been reported for synthesis silver sulfide nanoparticles (Ag2SNPs) such a template-based method at room temperature and ambient pressure (Xiao et al, 2002), water-in-CO2 microemulsions (Liu et al, 2004), a microwave-assisted template-free method (Su et al, 2016), modified homogenus precipitation route (Xaba et al, 2017), sonochemical synthesis (Du et al, 2007), hydrothermal method (Yu et al, 2012), by multi-solvent thermal decomposition method (Sahib et al, 2017), via a one-pot method in ethylene glycol with 3-mercaptopropionic acid (Kubie et al, 2011), modified chemical bath deposition technique (Jadhav et al, 2013), synthesis of silver sulfide nanoparticles capped with either chitosan, green tea, Combtretum molle or black wattle extracts (Sibiya and Moloto, 2018), conversion of silver thiolate polymers with sodium sulfide in a dual-phase solution preparation (Schaaff and Rodinone, 2003), metal-reducing bacterium Shewanella oneidensis MR-1 (Debabova et al, 2013), chemical method (Zhao and Song, 2014), multi-solvent thermal decomposition www.bosaljournals/chemint/ editorci@bosaljournals.com method (Khaleelullah et al, 2017), sonochemistry method (Kang et al, 2018) hydrochemical bath deposition from aqueous solutions (Sadovnikov et al, 2016) and nucleation process (León-Velázquez et al, 2010). These methods and routes for synthesis silver sulfide nanoparticles have many disadvantages due to toxic chemicals used and waste products, which create a problem to environment, also high energy consumption, difficulty of large-scale of processes and wasteful purifications (Cárdenas Riojas et al, 2019;Deshmukh et al, 2019;Fletcher et al, 2019;Huang et al, 2019;Maharubin et al, 2019;Sadovnikov, 2019).…”
