Synthesis of highly photostable NIR-emitting quantum dots CdTeSe/CdS/CdZnS/ZnS

One-pot synthesis of polythiol ligand for highly bright and stable hydrophilic quantum dots toward bioconjugate formation

“…The values of 1.27, 2.77, and 2.67 were obtained for the conjugates with emission peaks of 600 nm, 640 nm, and 680 nm, respectively. Thus, the conjugates QDs-PTVP-Ab with fluorescence maximum in a range of 640-680 nm were most suitable in LFA for the detection of ADV gB since the background intensity in this area of spectrum is low [48].…”

“…QDs CdTeSe/CdS/ ZnS (640 nm) and CdTeSe/CdS/CdZnS/ZnS (680 nm) were synthesized according to our previous publication [48] using 1% mol and 3% mol of Te in core composition. The outer ZnS shell was prepared using a single precursor method [49].…”

Cadmium-Based Quantum Dots Alloyed Structures: Synthesis, Properties, and Applications

“…Table 3 shows different photovoltaics based on alloyed quantum dots as sensitizers. Quantum dots are valuable nanostructure materials that represent a great candidate for light emitting diodes (LEDs) [88][89][90][91] because of their optical properties that can be changed with sizes, such as bandgap and large photostability, for core/shell models such as CdTeSe/CdZnS QDs that showed higher stability over UV radiation compared to the binarybased CdTe/CdSe QDs [92]. Additionally, external quantum efficiency (EQE), which represents the numerical percentage between the electrons injected by the device and the emitted light, recorded good values up to 23.68 and 27.6% for CdZnSeS/ZnS and CdZnSeS/ZnS/oleic acid QDs, which can be improved depending on the shell applied [93][94][95][96][97].…”

The systematic study of the precursor ratio effect in the Cd–Zn–S quantum dot synthesis

“…Also, the obtained CdxZn1-xS QDs have rather narrow emission bands (FWHM is in the order of 20 nm) at significant Stokes shift values (≈ 25 nm), see Table 6. These parameters of CdxZn1-xS QDs allow them to be promising candidates for use in medicine as biomarkers [54,55] and the production of LEDs [56,57]. An important characteristic of QDs as scintillators is their PL lifetime.…”
