2013年9月1日 · Nanocrystals (NCs) of II–VI semiconductors of few nanometers average size, called quantum dots (QDs), are now intensely investigated as radiation detectors.

2020年3月16日 · A novel nanohybrid of graphene-based Cu 2 ZnNiSe 4 with WO 3 nanorods (G-CZNS@W) was successfully synthesized via a simple hydrothermal method to use as a counter electrode (CE) for...

1997年11月13日 · We report a synthesis of highly luminescent (CdSe)ZnS composite quantum dots with CdSe cores ranging in diameter from 23 to 55 Å. The narrow photoluminescence (fwhm ≤ 40 nm) from these composite dots spans most of the visible spectrum from blue through red with quantum yields of 30−50% at room temperature.

Compared with the traditional semiconductor quantum dots, CDs have the advantages of a small particle size, good dispersion, low environmental pollution, and high biocompatibility, and its many...

Similarly, carbon dots (CDots) and quantum dots (QDs) are useful tool in cancer imaging [178] and are utilized for detection of earlystage TNBC. Not only this, but chemokine receptor type also...

2019年3月21日 · In this work, we report the synthesis of CdZnSe–CdZnS core–shell alloy QDs through a Cu-catalyzed solid solution alloying strategy starting from CdSe–CdS core–shell QDs. The resulting CdZnSe–CdZnS alloy QDs exhibit emission profiles covering a wide wavelength range of 470–650 nm while maintaining high photoluminescence quantum yields.

碳粒子芯也可以与无机盐掺杂如表面功能化前的ZnS以显著提升荧光亮度（CZnS-Dots，图解1）。 9这些碳点已经成功用于体外细胞成像和双光子激励。 7,9,10

2013年12月1日 · Binary CdS and ZnS and ternary CdZnS alloy quantum dots (QDs) were synthesized via a simple, inexpensive, and reproducible route using sulfur, cadmium stearate, and zinc stearate as precursors and N-oleoylmorpholine as the reaction medium and solvent. Both binary and ternary QDs exhibited a narrow size distribution and high crystallinity as ...

2014年1月1日 · Small size (d < 10 nm) II–VI semiconductor nanoparticles (NPs) doped with transition metal ions (TMIs) have been intensely investigated during the last two decades in search for superior or even new optical, electrical and magnetic properties, associated with the reduced size, for a wide range of technological applications [1 – 3].

2017年12月1日 · The as-prepared CdZnS/ZnSe quantum dots show good color tunability, which is ranging from deep-blue to red. Bright white LEDs are fabricated by appropriately integrating a mixture of red, yellow and green emissive CdZnS/ZnSe quantum …
