Cadmium selenide semiconductor nanopowder is an inorganic compound with the formula CdSe. That is classified as II-VIsemicondutor of the n-type. CdSe-derived nanoparticles with sizes below 10 nm manifest a property known as quantum confinement. Quantum confinement defines when the electrons in a material are confined to a very small volume. Quantum confinement is size-dependent phenomenon. It means the properties of CdSe nanoparticles are tunable based on their size. Crystal structure of CdSe is available in three forms such as Wurtzite(hexagonal), sphalerite(cubic), rock salt(cubic).
Cadmium selenide is a semiconducting material. However, it has yet to find many applications in manufacturing. This material is transparent to infra-red (IR) light and has seen limited use in windows for instruments utilizing IR light. CdSe nanoparticles have received a lot of attention because of their unique optical and electronic properties. This nanopowder can be utilized as an efficient electron acceptor in the composites with various conjugated polymers. Because of its high photosensitivity, it has been employed as a photoconductive device.
Cadmium selenide semiconductor nanopowder is used in optoelectronic devices, laser diodes, nanosensing, and biomedical imaging. This powder is also utilized in high-efficiency solar cells. These nanocrystals possess characteristics that make them attractive for optoelectronic applications, for instance, light-emitting diodes (LEDs), solar cells and biological markers.
The fluorescence spectrum is size dependent on the CdSe nanoparticles. So this property can be used by engineers. Engineers are able to manufacture laser diodes that cover a large part of the electromagnetic spectrum by using the size-dependent fluorescence spectrum. Doctors are instigating these materials for use in biomedical imaging applications. Human tissue is permeable to far infra-red light. By injecting appropriately prepared CdSe nanoparticles into injured tissue, it may be possible to image the tissue in those injured areas
