Does quantum confinement change the properties of CdSe and CdTe?

This work is focused on study of CdSe and CdTe semiconductor quantum dot and corresponding change in their properties by quantum confinement. The applications along with different dopant ion have been summarised through table and supported by literature.

What is the difference between CdSe quantum dots and cdots?

The difference between CDSE quantum dots and Cdots is explained in the literature relative to their behavior under excitation wavelength. CDOTs emission maxima mainly depend upon the excitation wavelength in contrast to the conduct of many quantum dots.

Which semiconductor quantum dot is suitable for different applications?

Among all semiconductor quantum dot, CdSe and CdTe have been studied lot due their unique optical and electronic properties. The reports suggest that CdSe and CdTe are suitable material for various applications . The applications of quantum dot have proved its importance for improving human life.

What are the properties of quantum dot?

In case of quantum dot, the motion of charge carriers is restricted in all dimension i.e. along length. width and thickness. The important properties of quantum dot include large surface to volume ratio, enhancement in band gap and change in electronic property .

What is the most effective method for CdSe quantum dot synthesis?

Among all these methods the most effective method for fabrication CdSe quantum dot is hot injection method. 3. Hot injection method for CdSe quantum dot synthesis The hot injection is well stabilised method and have been adopted by scientific fraternity around the world.

How can spectroscopy be used to study quantum dots?

Transmission electron microscopy and UV–Vis spectroscopy can be used to observe the individual crystallite morphology and the origin of optical activity of quantum dots (QDs). CdSe QDs with different sizes were obtained by controlling their growth time, and the estimated sizes of the CdSe QDs ranged from 2.5 to 5.1 nm.
