From Theory to Reality: The Quantum Dot Journey
For decades, scientists have recognized the theoretical potential of nanoparticles to display size-dependent quantum effects. However, many considered it nearly impossible to create particles with such minuscule dimensions that could harness these quantum phenomena for practical applications.
In a groundbreaking development, Russian solid-state physicist Alexei Ekimov, during the early 1980s, successfully harnessed size-dependent quantum effects in colored glass. This achievement was attributed to nanoparticles of copper chloride, where Ekimov demonstrated that the particle’s size directly influenced the glass’s color, thanks to quantum effects.

Scientific Milestones: Leading to Quantum Dot Revolution
American scientist Louis Brus emerged as the first individual worldwide to demonstrate these size-dependent quantum effects in particles suspended in a fluid medium. Complementing this achievement, American scientist Moungi Bawendi, in 1993, ushered in a revolutionary breakthrough by devising a chemical method for the production of quantum dots. This innovative approach enabled the creation of nearly perfect quantum dot particles, marking a pivotal moment in the field.
