Production of colloidal quantum dots with 10-kg capacity

Among the many subsets of nanomaterials, quantum dots are like no other. At dimensions typically below 10 nanometers, nanocrystalline semiconductors, metals, and magnetic materials can all exhibit quantum confinement phenomenon. Basically, at the nanometer scale, their hysical size encroaches upon the fundamental quantum confinement dimensions of orbiting electrons that are uniquely prescribed by their atomic nucleus.

Quantum dots from one material of different sizes glow with different colors. In comparison with traditional florescent materials, quantum dots possess greater photostability and their color remains stable over several years.

Current and future applications of QDs impact a broad range of industrial markets. These include biology and biomedicine; computing and memory; electronics and displays; optoelectronic devices such as LEDs, lighting, and lasers; optical components used in telecommunications; and security applications such as covert identification tagging or biowarfare detection sensors.

Areas of application

  • Security
  • LEDs
  • Labeling studies
  • Medicine
  • Future uses: solar modules, flexible electronics, and optoelectronic devices


  • Producers of LEDs, biomedical markers, and electronics

Competitive advantages

  • Variable wavelength of fluorescence spectrum
  • High photostability
  • Broad wavelength range
  • Low cost

Colloidal quantum dots are nanosized semiconducting crystal with florescent properties, which, because of their small size, also exhibit quantum properties that are characteristic of individual molecules and not inherent to macroscopic semiconductors. Absorbing radiant energy in the broadband, they emit a narrow spectrum of light waves whose length depends upon the size of the particle. Quantum dots from one material but of different sizes glow with different colors. In comparison with traditional florescent materials, the quantum dots possess greater photostability, and their color does not deteriorate over several years.

Structure of Colloidal Quantum Dots
Quantum dots—semiconducting crystals with sizes ranging from one nm to ten nm. The size of the nanoparticles provides the capabilities that distinguish the crystals from volume semiconductors.
