Abstract:

Alkyl-xanthato bismuth(III) complexes of the form [Bi(S₂COR)₃] where R= Me (1), Et (2), ⁿPr (3), ⁱPr (4), ⁿBu (5), ^sBu (6), ⁱBu (7), Pent (8), ⁱPent (9), ⁿHex (10), ⁿHept (11) and ⁿOct (12) have been prepared and characterised by infrared spectroscopy (IR), nuclear magnetic resonance (¹H and ¹³C) spectra and elemental analysis (EA).¹ Thermogravimetric analysis (TGA) has been applied to study the decomposition temperature for each complex. Then all complexes were used as single-source precursors for the formation of bismuth sulfide (Bi₂S₃) nanocrystals (NCs) at low temperature of 175 °C using melt method.² All synthesised metal sulfides from complexes (1) to (12) were characterised by powder X-ray diffraction (pXRD) and scanning electron microscopy (SEM). The powder X-ray diffraction patterns of Bi₂S₃ (NCs), which is indexed to orthorhombic lattice of bismuthinite revealed that, any change in the xanthate chain length can affect the growth along the (021) peak intensity, Figure 1.³ Despite the low temperature synthesis conditions, the Bi₂S₃ NCs exhibited good crystallinity in keeping with previous uses of metal xanthates complexes.

Figure 1: Powder XRD patterns of Bi₂S₃ NCs obtained [Bi(S₂COR)₃] where R= Me (1), Et (2), ⁿPr (3), ⁱPr (4), ⁿBu (5), ^sBu (6), ⁱBu (7), Pent (8), ⁱPent (9), ⁿHex (10), ⁿHept (11) and ⁿOct (12) precursors at 175 ^oC using melt method.

nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.

MATSUS

Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.

International Conference on Hybrid and Organic Photovoltaics

International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.

Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics

The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.

International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics
