One-pot Microwave Assisted Synthesis of Homogeneously Alloyed CdSe Te1- Nanocrystals with Tunable Photoluminescence

Electrochemiluminescence energy transfer-promoted ultrasensitive immunoassay using near-infrared-emitting CdSeTe/CdS/ZnS quantum dots and gold nanorods

“…The quantum yields (QYs) were estimated at room temperature using Rhodamine B, and Rhodamine 6G in ethanol according to the different maximum emission wavelengths of thequantum dots3266.…”

“…Meanwhile, the parent CdSe QDs can only cover typically 480–620 nm in emission, and even the CdTe QDs of 7 nm can only reach ~720 nm in emission192728. To date, various methods have been developed for the synthesis of single or core-shell structured CdTeSe QDs202829303132. Nevertheless, most of these methods adopted high-temperature organometallic routes, and then additional complicated manipulations were required to disperse these QDs in water, leading to the decrease of quantum yield (QY) and the limitation for their further bioapplications1933.…”

Near-infrared emitting CdTeSe alloyed quantum dots: Raman scattering, photoluminescence and single-emitter optical properties

“…Many fabrication methods have been studied and improved to synthesize CdTeSe QDs with core/shell structure, [14][15][16][17][18][19] and different kinds of shells such as ZnSe or ZnTe have been reported lately. 20 Due to the reactivity difference between Te and Se, a CdTe-rich core and CdSe-rich shell have been formed in the CdTeSe alloy with the formation of a gradient type II.…”

CHAPTER 11.5. Nanoparticles and Quantum Dots

“…Based on the successful synthesis of core QDs, our group developed the MI-assisted method and successfully synthesized high-quality CdTe/CdS, CdTe/CdS/ZnS core-shell structure QDs (Figure 11.5.12). 82,129 Other II-VI QDs synthesized by the MI method have been reported recently including CdSe x Te 1Àx , 130 CdSe, 131 CdSe/ZnS, [132][133][134] CdSe/CdS/ZnS, 135 ZnSe, 136 and ZnSe: Mn/ZnS. 137 …”
