Investigation of the room-temperature solid-state reactions leading to ZnS nanotubes and the third-order nonlinear optical properties of the nanotubes obtained

Abstract

The room-temperature solid-state reactions occurring in the preparation of nanotubes of zinc sulfide are further investigated by x-ray powder diffractometry (XRD) and infra-red (IR) spectrometry measurements, and the nanotube ZnS product obtained is measured by Z-scan technology to investigate the third-order nonlinear optical (NLO) properties. The XRD result suggests that the reactions leading to the formation of the nanotubules have occurred through reaction-controlled to growth-controlled procedures, and the IR result indicates that the procedures involve a coordination effect of the additive DABCO as ligand on the reactant. The result of NLO measurements shows that the nanotube ZnS products obtained have the behaviours of the third-order nonlinear optical properties of both NLO absorption and NLO refraction with self-focusing effects.

Third-order nonlinear optical properties of Bi2S3 and Sb2S3 nanorods studied by the Z-scan technique

“…The larger w (3) values of Sb 2 S 3 nanosrods and Bi 2 S 3 nanorods may relate to the geometrical and electronic structures [35,36]. It is reported there is a general tendency for optical nonlinearities to be larger in 1D nanomaterials [27,28]. …”

“…One-dimensional Bi 2 S 3 and Sb 2 S 3 nanomaterials have been synthesized by hydrothermal and solvothermal methods [19][20][21][22][23][24]. Recently, NLO properties of 1D nanomaterials aroused much more attention because of their unique geometrical and electronic structure [25][26][27][28]. However, less has been done to characterize the NLO properties of nanomaterials with different geometries.…”

Hydrothermal synthesis of transition-metal sulfide dendrites or microspheres with functional imidazolium salt

“…However, considerable efforts have been devoted to the preparation of transition-metal sulfide semiconductors [10][11][12]. Many methods have been exploited to prepare these metal sulfide semiconductors, such as microwave irradiation [13], pyrolysis [14], vesicles [15], organic-metallic precursor [16,17], hydrothermal synthesis [18], solid reaction [19] and so on.…”

“…Room temperature ionic liquids (ILs) have been widely investigated as a new kind of reaction media owing to their unique properties such as low volatility, nonflammability, high chemical and thermal stabilities, designable structures, high ionic conductivity, broad electrochemical windows, etc [19]. Recently efforts have been focused on the fabrication of inorganic materials with novel and improved properties using ILs as templates or cosolvent systems [20].…”

Solid state synthesis of hydrous ruthenium oxide for supercapacitors

“…Moreover, crystalline powders can be prepared by directly mechanical mixing of raw materials and the need for subsequent chemical treatment is eliminated. Recently, Xin and his colleagues [17][18][19] have proposed a simple solid state reaction for preparation of a series of nanocrystal oxides and sulfide. In their process, the precursors of metal oxide were obtained by directly mixing the corresponding metal salts and alkalis with or without surfactant in a mortar at room temperature.…”
