Stockholm, Sweden - A trio of US-based researchers on Wednesday won the Nobel Chemistry Prize for developing tiny "quantum dots" used to illuminate TVs and lamps, hours after a prematurely sent statement revealed their names.

French-born Moungi Bawendi, Louis Brus of the United States, and Russian-born Alexei Ekimov brought advances on tiny particles that "now spread their light from televisions and LED lamps, and can also guide surgeons when they remove tumor tissue," the jury said.

But a rare leak led to the winners' names being mistakenly sent to media outlets hours before they were officially announced, prompting an apology from the awards' overseers.

Hans Ellegren, Secretary General of the Royal Swedish Academy of Sciences, said a press release went out for "still unknown reasons."

"We deeply regret that this happened. The important thing is that it did not affect the awarding of the prize recipients in any way," Ellegren said during a press conference.

Bawendi told reporters he had not heard the news before receiving the call from the Nobel Committee.

"I didn't know, I was awakened by the Swedish Academy. I was sound asleep," he said via telephone during a press conference, noting he had not expected the call.

Bawendi listed his feelings as "very surprised. Sleepy, shocked. Unexpected and very honored."

Nobel leaks are rare, with the various prize-awarding academies going to great lengths to keep the winners' names under wraps until the announcements.

Bawendi (62), born in Paris to French and Tunisian parents, is a professor at Massachusetts Institute of Technology (MIT) in the United States.

Brus (80) is a professor at Columbia in New York, and Russian-born Alexei Ekimov (78) was formerly the chief scientist at the US-based Nanocrystals Technology.

According to the jury, physicists had "long known" about the quantum effects that could arise in nanoparticles, but previously it was "impossible to sculpt in nanodimensions."

In the early 1980s, Ekimov "succeeded in creating size-dependent quantum effects in colored glass," and a few years later, Brus was the first "to prove size-dependent quantum effects in particles floating freely in a fluid."

"In 1993, Moungi Bawendi revolutionized the chemical production of quantum dots, resulting in almost perfect particles. This high quality was necessary for them to be utilized in applications," the jury explained.

In addition to their current use, they are believed to to be able to contribute to flexible electronics, tiny sensors, thinner solar cells, and encrypted communication in the future, with the Academy noting that "we have just started exploring the potential of these tiny particles."

The trio will share the award of 11 million Swedish kronor (around $1 million) and will receive the prize from King Carl XVI Gustaf at a ceremony in Stockholm on December 10, the anniversary of the 1896 death of scientist Alfred Nobel who created the prizes in his last will and testament.

The chemistry award is the third Nobel of the season after the medicine prize and the physics prize were announced earlier in the week.

In medicine, RNA researchers Katalin Kariko and Drew Weissman were honored Monday for their groundbreaking technology that paved the way for mRNA Covid-19 vaccines.

The physics prize on Tuesday went to France's Pierre Agostini, Hungarian-Austrian Ferenc Krausz and Franco-Swede Anne L'Huillier for research using ultra quick light flashes that enable the study of electrons inside atoms and molecules.

The highly watched literature and peace prizes, will be announced on Thursday and Friday respectively.

The Economics Prize – created in 1968 and the only Nobel not included in the 1895 will of Swedish inventor and philanthropist Alfred Nobel founding the awards – closes out the 2023 Nobel season on Monday.
