应用

CdSe/ZnS core/shell nanocrystals in solid form are highly purified quantum dots. They can be dispersed in most non-polar organic solvents such as toluene, chloroform, hexane, etc. With very low organic impurity, these quantum dots are specifically designed as emitters for optoelectronic applications such as display and solid state lighting.

Protocol to make QD solutions (dispersing QDs into solutions):

1. Weigh desired amount of the quantum dot powder and put it in a glass vial;
2. Add desired amount of the solvent, i.e. toluene, chloroform, hexane, etc. (mostly non-polar organic solvents) in the vial and shake the vial;
3. If there is any solid left in the vial after shaking, sonicate the vial for 30~60 seconds to get the quantum dot powder well dispersed. If required dilute the solution further.

Material has a shelf life of around 3 years if stored properly. Store at room temperature (4-25 °C); do not freeze. Should not be exposed to extreme temperatures.

Quantum dots are tiny particles or nanocrystals of a semiconducting material with diameters in the range of 2-10 nanometers.

量子点是一种微小颗粒或纳米晶体,即直径在2-10纳米之间的半导体材料。

Since the first report of the low-cost dye-sensitized solar cell (DSSC) in 1991 by Gratzel and his coworker,1 dye-sensitized solar cells (DSSC) has been regarded as one of the most promising photovoltaic technologies because of their transparent and colorful characteristics, as well as low cost.

Professor Sharma and colleagues review the synthesis and applications of this novel material. This includes a discussion of the unique properties of quantum dots and their suitability for solar cell applications, along with common synthesis techniques used to develop these materials.
