Abstract
A method for fabricating quantum rods includes: preparing a Cd-precursor; preparing a S-precursor and CdSe seeds; preparing a Zn-precursor; mixing the S-precursor and the CdSe seeds with the Cd-precursor in a reaction mixture; adding the Zn-precursor to the reaction mixture; stopping the reaction; and performing a purification process to obtain the quantum rods.
Claims20
A method for fabricating quantum rods, comprising:
- preparing a Cd-precursor;
- preparing an S-precursor and CdSe seeds;
- preparing a Zn-precursor;
- mixing the S-precursor and the CdSe seeds with the Cd-precursor in a reaction mixture to initiate CdS shell growth over the CdSe seeds;
- after initiating the CdS shell growth, adding the Zn-precursor to the reaction mixture;
- stopping the reaction;
- and
- performing a purification process to obtain the quantum rods.
