Cadmium selenide (CdSe) is a well-known inorganic semiconductor with exceptional electrical and optical properties that have been demonstrated for use in a wide range of devices, including energy harvesting applications. Due to their fascinating features in both bulk and industrial applications, nanosized materials are the focus of interest in many sectors today.
Quantization and surface area play a significant part in the amazing changes in characteristics of nanomaterials that result from the material’s physical size being shrunk to nanoscale dimensions. Nanomaterials come in a wide range of geometries and forms, such as three-dimensional nanospheres and nanoparticles, two-dimensional nanosheets and thin films, one-dimensional nanowires and nanotubes, and zero-dimensional quantum dots.
The potential of various semiconductor QDs has been investigated for photovoltaic devices among the nanoscale materials, lasers, light-emitting diodes, field effect transistors, and biological uses. Contrarily, CdSe is one of the compound semiconductors that has proven its viability in a variety of applications, including photodiodes, solar cells, lasers, biological fluorescent labels, and optical amplifiers.
Scientists are mainly interested in CdSe QDs because of their 3-dimensional quantum confinement and high surface to volume ratio among the numerous CdSe nanostructures. Recently, scientists used a variety of ways to produce CdSe QDs with various crystal shapes.
Wurtzite, zinc blende cubic, and rock-salt formations are some of the more well-known CdSe QD structures. However, a lot of research has been done on CdSe QDs’ optical, optoelectronic, biosensing, and electrical capabilities.
The Global CdSe quantum dot Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
CdSe quantum dots launched by Alfa Chemistry. Quantum dots have gained a lot of attention from the electronics industry due to their distinctive qualities, such as enhanced photostability, high extinction coefficient and brightness, significant Stokes shift, and use in quantum computing and medical imaging.
The ZnS coating on the CdSe ZnS core shell quantum dots, which has a purity of 99+%, helps to stabilize and protect the core’s distinctive optical properties from potentially harmful environments while also lowering surface trap states and enhancing performance. Bright and stable luminescence is produced by the ZnS shell, and their stability for additional surface-chemistry manipulation.
