Surfactant-assisted solvothermal synthesis of Bi2S3 nanorods

Low‐temperature urea‐assisted hydrothermal synthesis of Bi2S3 nanostructures with different morphologies

“…Using thioacetamide (CH 3 CSNH 2 ) as the sulfur source to control the morphology of Bi 2 S 3 in the solution phase has been previously investigated [25][26] nuclei in the reaction system. With a further hydrothermal treatment, these crystalline nuclei then continuously grow along the rod-shaped micelles, and in the end of one-dimensional nanorods of monocrystalline structure.…”

Controllable synthesis and luminescence of YPO4:Ln3+ (Ln = Eu and Sm) nanotubes

“…It is well known that SDS is a type of hydrophilic surfactant containing negative groups and SDS molecules will organize into cylindrical micelle if the concentration exceeds a certain critical value. These anisotropic structures can be used as templates to promote the formation of 1D nano/micro materials [37]. As soon as the nitrates are added into the solution, Y 3?…”

Polymer-assisted hydrothermal synthesis of Bi2S3 nanostructured flowers

“…SAED patterns (Figs. 3e and 5d) of a nanorod and nanoplate of the microsized flowers show a single crystal of Bi 2 S 3 [9] with the [1 0 0] and [2][3][4][5][6][7][8][9][10] as zone axes, respectively. Simulated diffraction patterns [13] (Figs.…”

“…Bi 2 S 3 is one of these materials, which has been used as a lamellar structure with a 1.3 eV (2.08 Â 10 À 19 J) direct band gap [1,[4][5][6], and is a promising candidate for photovoltaic converters and photodiode arrays [4,6]. There have been several recent reports on hydrothermal and solvothermal productions of Bi 2 S 3 semiconducting materials: Bi 2 S 3 nanorods in water containing HCl [1] and tartaric acid [2]; single-crystalline Bi 2 S 3 nanorods [4]; irregular and agglomerated particles and rod-shaped Bi 2 S 3 crystallites in KOH-free and KOH-added solutions [5]; Bi 2 S 3 nanorods using Span80 and SDS as surfactants [6]; Bi 2 S 3 nanorods and nanostructured flowers in solutions containing 1-2 cm 3 HNO 3 [7]; and Bi 2 S 3 flower-like patterns with well-aligned nanorods in distilled water containing L-cysteine [8]. In the present study, Bi 2 S 3 clusters of nanorods and nanostructured flowers were hydrothermally produced in acidic solutions.…”
