Rapid Microwave Synthesis of Tunable Cadmium Selenide (CdSe)‎ Quantum Dots for Optoelectronic Applications

Abstract EN

Quantum dots (QDs) are a hot topic in optoelectronic device research, due to tailorable absorption and emission properties.

Unfortunately, the conventional methods of QD synthesis are hazardous and time-consuming.

In this work, we present an alternative method of fabricating cadmium selenide (CdSe) QDs (via rapid microwave synthesis).

This novel fabrication method provides a quick and efficient way to synthesize QDs that are almost identical to those commercially available.

We also demonstrate the tuning of QD sizes by varying time and temperature during the growth process.

Optical spectroscopy was used to measure the emission profile of QDs of various sizes.

With ease repeatability, tunability, and scalability, this QD synthesis method can be integrated into a wide range of applications and optoelectronic devices.
