Studies on highly luminescent AgInS2 and Ag–Zn–In–S quantum dots

Optical characterization of the AgInS2 nanocrystals synthesized in aqueous media under stoichiometric conditions

“…For decades, the I-III-VI 2 materials have attracted considerable attention for application in the areas of thin film solar cells, visible and IR lightemitting diodes, IR detectors, optical parametric oscillators, upconverters, and far IR generators. Development of the methods for synthesis of AgInS 2 nanocrystals (NCs) with a tunable band gap and a high photoluminescence (PL) quantum yield opened new prospects for their application in lightemitting devices [2,3], photovoltaic solar cells [4] and lowtoxic photostable molecular probes [5,6]. Up to date, different strategies have been proposed for synthesis of the AgInS 2 NCs such as: hydrothermal [7], solvothermal [8,9] and hot injection methods [10][11][12][13][14][15], aqueous synthetic route [16] etc.…”

A new strategy for synthesizing AgInS2 quantum dots emitting brightly in near-infrared window for in vivo imaging

“…With a band gap of ~1.8 eV at room temperature, the AgInS 2 QDs can emit in the near-infrared region with high extinction coefficients, which offers an intriguing alternative for biological imaging applications 25 . So far, a variety of strategies have been established for the synthesis of AgInS 2 QDs [26][27][28][29] , most of which were carried out in organic phase and organic ligands were used as the capping agents for the QDs. Although…”

Synthesis and temporal evolution of Zn-doped AgInS2 quantum dots

“…Therefore, AgInS 2 eZnS/PMMA nanocomposite keeps the fluorescence properties effectively which have potential applications in the field of LED. And the electroluminescence (EL) spectra and luminance-current-voltage (L-I-V) characteristic of the obtained QD-LED was reports in our precious reports [9]. …”
