The simplest way of producing Cadmium Based Quantum Dots is directly generating semiconductor particles in gaseous or liquid phase, followed by their controlled condensation as nanoparticles. Again, the crystallinity and morphology of the resulting nanostiuctures can be guided by using templates or substrates on which the condensation is performed. This type of growth is called ‘epitaxial growth’, where the substrate (the template) and the growing semiconductor layer are having matching crystal lattice parameters.

Cadmium Based Quantum Dots are nanometer-sized crystals made of metallic or mostly of semiconductor materials. QDs nano-particles generally fall within 2–10 nm size range and possess tunable optical and electrical properties. QDs were found as an alternative to organic dyes and fluorescent proteins and thus they can be used for various biosensing purposes.

The potential applications of Cadmium Based Quantum Dots cover a wide area from production of energy to storage, electronics to photonics, biomedical science to biotechnology and so on. Among these, QD based solar cell systems have received much attention. Tunable bandgaps of semiconductor allows the absorption of the broad spectrum of wavelengths that reach earth and there by fabrication of ‘rainbow solar cells’ are considered. Another aspect of recent interest is the multiple exciton generation efficiency in quantum dots, which boosts the light harvesting ability in QD based solar cells.

Another innovative application of Cadmium Based Quantum Dots is in modem biomedical analysis (cell imaging and targeting, therapeutics) and in the development of novel chemical sensors. The unique physicoehemical properties of QDs, coupled with the inherent increase in signal-to-noise ratio makes these systems promising candidates for sensing applications.” A detailed review on the use of QDs as biosensors, exploiting their outstanding properties.

Cadmium Based Quantum Dots semiconductor nanocrystals small enough to exhibit size-dependent properties, have generated tremendous interest due to their unique optical properties, including broad excitation spectra, narrow, tuneable and symmetric emission spectra covering the wide range of spectra from visible to infrared, excellent photostability, and large quantum yield.
