This demonstration video shows how an OLED is synthesized and produced in a lab. For questions feel free to leave a comment and don't forget to subscribe!
Their is some leakage in the emissive layer. Probably due to the aluminium contacts. The device is just degrading as you leave it on. You can tell after he leaves he device powered on for a second or two. Parts of the cell begin to die and turn dark. I read in a paper that if you replace the aluminum contacts with Graphene it glows brighter without the leakage. (Dark spots).
Weer een Nederlands accent! Misschien lijkt het maar zo, maar waarom bestaat de RUclips community met de kennis en kunde om op video een succesvolle, werkende hoge kwaliteit OLED te maken (bijna) volledig uit Nederlanders? (Granted, dat is wel aannemende dat jij ook een Nederlander bent, maar aangezien je accent ben ik daar 99% zeker van) De RUclips OLED manufacturing community lijkt wel volledig overgenomen te zijn door onze mede-Nederlanders. Je zou ook wel kunnen zeggen dat wij de RUclips OLED community volledig hebben... *G E K O L O N I S E E R D* ! Nu alleen nog een manier vinden om er een slaatje uit te slaan, net zoals men deed in de gouden eeuw. Ja, _die_ gouden eeuw! Ook wel bekend als de goede oude tijd van de VoC, toen wij Nederlanders nog praktisch regeerden over het zuidelijk halfrond. En dan kies ik er bewust voor om de alom bekende, zeer beruchte impopulaire zwarte bladzijde uit onze geschiedenis expres even buiten beschouwing te laten. Discussies over de hoeveelheid roet in het gezicht van Zwarte Piet en de huidskleur van Sinterklaas hebben wat mij betreft niets te zoeken in deze krochten van de RUclips sloppenwijk, ook wel bekend onder de Engelse naam: 'comment section'. 🤣 (Volledig satirisch bedoeld natuurlijk, het was absoluut niet mijn bedoeling om iemand te kwetsen met deze laatste alinea!)
You must understand that these are highly toxic compounds and some may be as toxic as methyl-mercury, which can seep right through nitrile and latex gloves! And, then there is the waste you must absolutely deal with properly! You cannot just dump it! You could poison you and your family AND your neighbors and your neighbors down the street and across the street!
@@1wow187 Even though this video has nothing to do with methylmercury or any other mercury compounds, methylmercury popped into my head too for some reason. I don't think any of these substances can penetrate nitrile gloves though.
Actually, that's not an OLED, but an Organic Light-Emitting Electrochemical Cell. It works in a slightly different way. OLEDs require contact materials with proper work functions. OLECs don't. A much simpler and quicker preparation can be found in the video "Preparation Of An Organic Light Emitting Diode" by Wisconsins Mrsec. (still that's not an OLED but an OLEC). In our labs we use an even simpler way, as can be found in many papers in the literature (and the working voltage -not current! - is 4.5V).
I've read that such cells have been used in biosensors and the mechanism is a classic example of reductive chemiluminescence in a transition metal complex.
Yay, I can make a OLED screen at home... 6:00 😰 I left my pressure gas chamber in my other pants. Any alternate way than that chamber? I have a sock and a zip lock bag...
"Get these chemicals and put them in a beaker" Okay... "Now stir them up on a hot plate" No problem... "Now suck them through a filter" Uhh.. I'll see what I have in the garage. "Now put them on a slide and spin them around really fast" I can probably do that. "Now put them in the antechamber" Starting to realize I might not be the target demographic for this tutorial...
Well you saw here what dissolves ruthenium. By soaking the soil in that then rinsing you can leach out the things you want. Then you need to evaporate the extra liquid, and you are left with a mixture of ruthenium and whatever else was leached out. Now you need to repeat the step with less liquid and use a chemical that favors the impurities and use a separatory funnel to remove the unwanted stuff. Repeat until you have your product.
Really hard to find so advanced videos on youtube or generally the internet. Many thanks!
True
got all the chemicals now i only need the million bucks for the equipment and will be ready to give it a go :P

So what is the concentration of the sodium hypophosphate??
RUclipsr: "be careful."
Methhead: "dude, I just got a new smidge that'll knock your socks off. "
It has very high acute toxicity and causes organ damage. It's not like meth...
9 volt current?

then why do you make cat videos if you're doing THIS

Great choice of music, and the tattoo is great too.
9 volt current. wtf is that?

I think you can use conductive tape or paste
Tnx! This worked! I have my own OLED now! Tnx a lot!
Hi, this is an excelent work. what is the role of sodium hypophosphite?
Well, sadly I lack all that millionary equipment but at least I'm healthy lmao 💀
"Get these chemicals and put them in a beaker"
Okay...
"Now stir them up on a hot plate"
No problem...
"Now suck them through a filter"
Uhh.. I'll see what I have in the garage.

I can probably do that.

Oh shit I'll get ready done this I wonder if the bank will give me a loan for this equipment good grief

Olá talvez você pode me ajudar, em uma solução que contém Ródio e Rutênio existe algum sal que eu consiga precipita um e depois outro?
9 volt is not a current

There is 200 tons of soil waste in my warehouse. There are about half a kilo of ruthenium in every 1 ton. How do I parse. I'm investigating.
