Quantum dots are synthesized nanoparticles that have many promising applications in medicine, photovoltaics, and LED’s. They usually range between 2-10 nm, and depending on their size, they will emit different wavelengths of light when illuminated by a UV light.
Determining the size distribution of quantum dots is important in helping determine synthesis routes. Historically, quantum dots have been difficult to measure because of the emission interfering with many instrument techniques. In this application note, the Partica CENTRIFUGE centrifugal nanoparticle analyzer was used to measure the size distribution of a 645 nm emitting red quantum dot sample (10 mg/mL).
