Quantum Dots

Quantum dots manufactured by Particle Works offer high-performance and narrow optical emission spectra.

Particle Works uses state-of-the-art, automated continuous flow microfluidic techniques and successive ionic layer adsorption and reaction (SILAR) to fabricate highly monodisperse andĀ batch-to-batch consistent quantum dots (CV values as low as 1% and 0.5% respectively). The resulting materials demonstrate up to 3x the performance compared to commercially available counterparts.

Optical properties of quantum dots, such as light emission and adsorption are determined by the size, shape and architecture of the underlying particles. Precision control over these particle parameters is crucial in achieving high performance materials that generate high quantum yields and narrow emission spectra. Peak material performance, such as high luminescence and narrow emission spectra, can only be achieved with highly monodisperse nanoparticles.
