Colloidal CdSe nanoplatelets (NPLs), also known as colloidal quantum wells, exhibit interesting properties such as narrow emission lines and atomic controlled thicknesses. To selectively tune the electrical and optical properties of these highly interesting nanomaterials, several methods have been developed to yield either core/shell or core/crown NPLs. Moreover, it has recently been shown that those NPLs can also be converted into nanorings with a toroidal topology.1 It is hypothesized that this new geometry exhibits interesting properties such as the presence of magnetoexcitonic states and terahertz absorption. Until know, not much knowledge has been obtained about this new geometric shape of CdSe.
In our research, we optimize the synthesis procedure of NPLs and subsequently etch the NPLs to obtain the characteristic ring-like geometry of nanorings. To reveal information about the obtained particles, we use a wide range of techniques such as time-resolved PL spectroscopy, single dot spectroscopy, AFM and TEM. From these experiments, the electrical and optical properties can be determined. As such, we take the first steps to extend the knowledge about this unexplored geometry of CdSe.

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.
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.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
