Low-dimensional systems such as quantum wells where the particle motions are confined in 1-dimensional space, quantum wires where the particle motions are confined in 2-dimensional space, and quantum dots where the particle motions are confined in 3-dimensional space are of great interest due to their superior properties compared to 3-dimensional structures due to their tunable physical, chemical, optical, and biological properties. With the development of growth techniques, it has become possible to obtain new generation core–shell quantum dots (CSQDs). CSQDs are lowdimensional semiconductor structures obtained by covering the core with a shell of higher bandgap material. The presence of a shell coated the core ensures chemical stability to the core and passivates the non-radiative recombination sites which results in strong photoluminescence quantum yield. CSQDs have potential applications in many fields such as photonics, optoelectronics and biology. In the biological field, several researchers have currently addressed some disease and virus detection issues such as cancer, coronavirus (COVID-19) and tumor imaging. CSQDs are typically synthesized from group II–VI, III–V, and IV–VI semiconductors. Studies have shown that shell thickness, impurity effects, dielectric mismatch, external fields and surrounding the core–shell quantum dots with different dielectric matrices significantly change the electronic and optical properties of these low-dimensional semiconductor structures. Therefore, in this section we wanted to talk about core–shell quantum dots, which have very interesting and fascinating properties.
