Plaque citation summarizing the achievement and its significance; if personal name(s) are included, such name(s) must follow the achievement itself in the citation wording: Text absolutely limited by plaque dimensions to 70 words; 60 is preferable for aesthetic reasons.
For discovery and synthesis of quantum dots, nanoparticles where their dimension determines their properties.
200-250 word abstract describing the significance of the technical achievement being proposed, the person(s) involved, historical context, humanitarian and social impact, as well as any possible controversies the advocate might need to review.
Louis E. Brus, a former Bell Labs researcher, was awarded the 2023 Nobel Prize in Chemistry on December 10, 2023 for “the discovery and synthesis of quantum dots.” Brus shared the prize with Alexei Ekimov and Moungi Bawendi for the development of these nanoparticles so tiny that their size determines their properties. These smallest components of nanotechnology now spread their light from televisions, LED lamps and solar cells, and they can also guide surgeons when they remove tumor tissue, among many other uses in cell biology research, microscopy and medical imaging. In its October 4 announcement, the Royal Swedish Academy of Sciences cited Brus for being “the first scientist in the world to prove size-dependent quantum effects in particles floating freely in a fluid.” Quantum dots are now used in a very wide array of optoelectronic applications due to their high efficiency and ease of tuning. They illuminate computer monitors and television screens based on QLED technology. They also add nuance to the ligh

Proposer email: Proposer's email masked to public
Please note: your email address and contact information will be masked on the website for privacy reasons. Only IEEE History Center Staff will be able to view the email address.
Street address(es) and GPS coordinates in decimal form of the intended milestone plaque site(s):
600 Mountain Avenue, Murray Hill, NJ 07974 40.684031, -74.401783
Describe briefly the intended site(s) of the milestone plaque(s). The intended site(s) must have a direct connection with the achievement (e.g. where developed, invented, tested, demonstrated, installed, or operated, etc.). A museum where a device or example of the technology is displayed, or the university where the inventor studied, are not, in themselves, sufficient connection for a milestone plaque.
Please give the address(es) of the plaque site(s) (GPS coordinates if you have them). Also please give the details of the mounting, i.e. on the outside of the building, in the ground floor entrance hall, on a plinth on the grounds, etc. If visitors to the plaque site will need to go through security, or make an appointment, please give the contact information visitors will need. Intention is to have the plaque just outside the main entrance to the Nokia Bell Labs facility in Murray Hill, NJ. Is both a corporate building and an Historic Site as other historical markers from IEEE are already on site both inside and outside the building.
Are the original buildings extant?
Yes
Details of the plaque mounting:
Outside the building on a rock or other permanent structure.
How is the site protected/secured, and in what ways is it accessible to the public?
The plaque will be prior to entering the building and thus there is no need to pass through security.
Who is the present owner of the site(s)?
Nokia America
What is the historical significance of the work (its technological, scientific, or social importance)? If personal names are included in citation, include detailed support at the end of this section preceded by "Justification for Inclusion of Name(s)". (see section 6 of Milestone Guidelines)
This discovery is historic in identifying when the size of a material system transitions the material properties from being determined classically to determined based on quantum behaviour at small size. This is a fundamental result which has now been extended greatly in material and biological research as well as exploited commercially by quantum dot monitors, displays, and televisions.
What obstacles (technical, political, geographic) needed to be overcome?
The key obstacle was to produce and isolate the nanoparticles at a semi-uniform dimension.
What features set this work apart from similar achievements?
Fundamental discovery of the performance of quantum size limited semiconductor dots and their application, as recognized by the Nobel Prize. This innovation is now ubiquitous in its application in many forms, including Quantum Dot video displays.
Why was the achievement successful and impactful?
This achievement in understanding lead to many practical application with great value, including video displays with high brightness and resolution.
