The video discusses about what are Quantum dots and why Nobel Prize in Chemistry 2023 is given to Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov.
The video majorly talks about 4 things:
1. What are Quantum Dots.
2. Which phenomenon are the based upon.
3. What were individual contribution of the three Nobel Laureate in this field.
4. What is importance of this discovery and future perspective.
In the video we will try to understand from very simpler perspective about the phenomenon and importance of quantum dots and how it is so useful to the humankind.

Hello Sir, you made it easy to understand what is a Quantum Dot. Super! Would like to point out two observations: (1) the presentation seems to addressed to Chemists or the students of chemistry. But you have made it simple enough for older ordinary folks like myself. I am probably the age of your grand father and yet I understood it! (2) ok, you HAVE to get out, ok, from the habit of, ok, saying ok after every other sentence. That would make your presentation much more attractive, and would prevent totally unnecessary distraction, ok! Thank you for the wonderful video and apologies to draw your attention to a minor, ok, bad habit 🙏🙏🙏

@padmahariharan6327 9 ай бұрын

Your presentation is so perfectly audience oriented that it felt good. I am 80. I am looking at India not being in the Nobel laureate list. It will be nice if you can make presentation on how Nobel committee is organised in finding out what has been done in the field of science by cataloging first and then deep review and evaluation by panel of multidisciplinary scientists including opposing view points, finally making the award each year to most eminent of the works studied by Nobel committee. Study of these review committee findings by Indian scientific community and students from science colleges across India will in time convert bright Indian minds from raw brain talent to future Nobel laureates. What do you think??

I have a question here.... Does the colour of nanoparticles that we see is because of it scattered the light of that colour so that means larger particle will absorb more energy of light and emit lesser energy light that will have longer wavelength and that's why larger naanoparticle will be reddish in colour! Am I right?

@katiemcguire3884 9 ай бұрын

I'm not sure I know how to explain this to non-chemist, but if you are interested look up quantum confinement and youll find out. Essentially the light (which is a wave) gets compressed at smaller sizes. The more compressed the wave the higher the energy and blue light has a higher energy than red :)

Sir , my doubt is that the smaller quantum dot should absorbs shorter wave lenth then the quantum dot should absorb Violet colour because Violet colour has shortest wave lenth when compared to blue colour, then why nanocrystles absorbs blue colour

@AllBoutChemistry 9 ай бұрын

That's a really interesting question Well the answer lies in the phenomenon of scattering You know the light of shortest wavelength is tend to scatter more coz it will interact with particles between the sample and our eyes and get scattered Probably most of the violet light is lost in such case and what reached us is kind of bluish Now I'm not saying that you will never get purple or violet colour It's like most of the small Quantum dots are bluish and when we say bluish we actually are talking about whole family of blue colour So indeed most of the quantum dots which are smaller are blue in colour but you may also get violet one (if ambient conditions are met)

@Ashutosh_Mukherjee 9 ай бұрын

Sir, I don't know if the question is silly or not. But as we know if a particle absorbs light of specific wavelength (for example red), it will emit its complementary colour so the particle would appear as the complementary coloured (here green as green is complementary to red according to VIBGYOR rule). Now, you said that the larger particle will absorb larger wavelength as wavelength is proportional to length of the box. So as they are absorbing larger wavelength they will emit shorter wavelength light. So when larger crystal is absorbing red light it must appear as green and when smaller crystal is absorbing blue light it must appear as yellow or orange. Please answer to my confusion sir.

@AllBoutChemistry 9 ай бұрын

Your question is very correct and the explanation you provided is correct as well. There are Quantum dots which are fluorescent even an image which I showed of colourful fluids that's also fluorescent Quantum dots that work on the principle of emission of light and the colour of emission will be exactly complimentary to the colour of absorbance (as explained by you) I intentionally didn't went into complimentary colour concept coz it could have confused many who don't know much about it To keep it simple we just mentioned that colour is specific to size But indeed your explanation is correct about complimentary colour

@katiemcguire3884 9 ай бұрын

@@AllBoutChemistry This isn't true. QDs are excited by a vast range of UV/blue light. The exact colour is complementary but is related to the band gap between the valance and conduction band. This changes as confinement is increased.
