Direct Preparation of Sulfide Semiconductor Nanoparticles from the Corresponding Bulk Powders in an Ionic Liquid

Abstract

Just add liquid and stir: Dispersions of metal sulfide nanoparticles (CdS, ZnS, PbS, and MnS) can be prepared directly by mixing the corresponding bulk solid with an appropriate ionic liquid, without further additives or solvents (see scheme). The selection of the ionic liquid is critical for the viability of this nanoparticle preparation method.

Luminescent lanthanide barcodes based on postsynthetic modified nanoscale metal–organic frameworks

“…The synthesis method of IL-MOF-Ln is similar with preparing functional ionic liquid incorporated semiconductor nanoparticle (details see supporting information). 24 The IL-MOF-Ln is clear (about 70 C) and could emit the luminescent barcoded signal under 330 nm (Fig. 6b and c).…”

Bis((dialkylamino)alkylselenolato)metal complexes as precursors for microwave-assisted synthesis of semiconductor metal selenide nanoparticles of zinc and cadmium in the ionic liquid [BMIm][ BF4]

“…Due to their unique physicochemical properties ionic liquids, especially room temperature ionic liquids like 1-butyl-3-methylimidazolium tetrafluoridoborate, [BMIm] [BF 4 ], have recently received attention as media for the synthesis of different types of nanoparticles [16][17][18][19][20][21] and inorganic materials [22,23] such as metal oxides including ZnO [24] or CuO semiconductor nanoparticles [25,26], metal chalcogenides [27,28], polynuclear metal complexes [29][30][31]. Among others, the properties of ILs include a high dielectric constant, polarity, thermal stability and a negligible vapor pressure.…”

“…Accordingly, a variety of different techniques and methods has been employed, including solvothermal [35][36][37][38], sol-gel [39][40][41], electrodeposition [42,43] and radiation assisted syntheses [44][45][46][47][48][49][50]. However, reports about the preparation of semiconductor nanoparticles in ionic liquids are quite rare [15,27,51,52]. There are gaps, for example in the selection of suitable precursors and methods, as well as in the investigation of the growth and shape-determining processes.…”

Luminescent Hybrid Ionogels Functionalized with rare Earth fluoride Up‐conversion Nanocrystals Dispersing in Ionic Liquid

“…Recently, the preparation of functional nanocrystals in ionic liquid media has aroused people's wide concern. Metal oxide nanoparticles, metal chalcogenides and fluorides have been prepared by the utilization of different ionic liquids. For instance, sulfide semiconductor (CdS, PbS, ZnS) nanoparticles are synthesized in the ionic liquids 1‐ethyl‐3‐methyl‐imidazolium ethylsulfate .…”
