Synthesis Strategies of Doped QDs

The implementation of synthesis strategies for doped QDs (QDs) is of paramount importance in the customization of their electronic and optical characteristics, thereby facilitating their utilisation in a diverse array of fields such as optoelectronics, biomedicine, energy, sensing, and others. This abstract presents a succinct summary of the synthesis methodologies utilised in the fabrication of doped QDs (QDs). The aforementioned tactics encompass codoping, post-synthetic doping, ion exchange, alloying, and core-shell architectures. The process of codoping entails the concurrent introduction of multiple dopants during the synthesis of QDs, thereby enabling accurate regulation of their concentration and amalgamation. The process of post-synthetic doping involves the introduction of dopants onto pre-synthesized QDs (QDs) through surface modification or ligand exchange procedures. The process of ion exchange involves the substitution of dopant ions for the original cations or anions present in the lattice of QDs. The process of alloying involves the combination of distinct semiconductor materials, with the inclusion of dopants during the alloying procedure. Core-shell architectures facilitate the encapsulation of doped QDs (QDs) within a safeguarding shell, thereby providing the ability to regulate dopant diffusion and associated characteristics. The utilisation of synthesis strategies offers a degree of adaptability in customising the characteristics of doped QDs to suit particular applications. The objective of future investigations in this domain is to devise novel doping methodologies and refine current techniques with the aim of augmenting the efficacy and broadening the scope of applications of doped QDs.
