What are Quantum Dots?

NIBIB's 60 Seconds of Science explains how quantum dots work and why they glow.

Congrats to the Nobel laureates Bawendi, Brus and Ekimov for their quantam dot discovery!

Thabnk you very much for the easy simplified explanation

[Kolumaic]

I actually know less about quantum dots for having watched this video, guess I'll try another channel.

Mine is blue colored mostly but I have diluted to very low extent. Lesser energy means lesser frequency right??

[dianegru]

if someone uses them for evil purposes, how can you remove them from the body

Quantum Dots are not technically "Quantum, " nor are they "Dots". What are they? NIBIB's 60 Seconds of Science explains:

:33 1 nanometer is approximately the width of 10 silicon atoms - not 2. Mistake probably came from looking at a logarithmic data set.

I need to write an introductory technical paper on quantum dots for uni assingment(history to present, 20 pages), can you recommend some good source with comprehensive explanation on the subject. Articles, rsearch papers, lectures or books?

[Eric-yjxg]

is it toxic? could it be used as tattoo ink?

[greatjojek]

Not higher/lower energy sound waves but higher/lower frequency

[subhradipporel]

you just mentioned about the compound of very small dimension capable of emitting different radiations ... nnow where is the concept of quantum, let alone be dots? I mean we all know atoms do thsi kind of emission spectra.

They forgot to tell us that its in the jabby jab

[divasg]

Quantum dot is inside the nano technology.

Our chemistry teacher not teaching properly

[ToxicallyMasculinelol]

explained virtually nothing about quantum dots. what a great use of taxpayer dollars. thanks for the pop science government!

[jerrylion]

A dot is a dot afcourse afcourse and noboday talks to a dot afcourse.

[blurglide]

You're confusing energy with frequency

[cynthiarosa]

The song and the woman’s voice yell: here comes bullshit.

[TheBigBanggggg]

Another video that doesn't want to inform, but only wants to say "Hey, we're here!"

i wanna put quantum dots in my skin so the store knows im vaccinated so i can shop ! science !
