"Glow in the Dark" How to make a Pemanent Reusable Glow stick

[FutureLaugh]

WOW!!! it barely works.

[whatsupandnew]

i am doing this for the science whoop whoop

[Poet0fDarkness666]

so many big words O_O

[discaras]

so to dope the zinc sulfide

you mix zinc sulfide with copper chloride or nitrate ?just that?

[Teseia]

where should i buy copper doped Zinc Sulfide?

[MasterChief241]

where did you get the syringe

[MasterChief241]

where did you get the syringe

[chrisofcolombia]

I know how to make Zinc Sulphide. can you tell me how to dope the ZnS with copper? Where I live, commercial glow-in-the-dark powder is hideously expensive, and online purchase out of the question. Thanks.

[Cforchemistry]

you can try to doped the Zinc sulfide via trace amount addition of copper nitrate or chloride. I am still experimenting with it, so please feel free to explore.

[chrisofcolombia]

Thanks for the reply.

I have heard that one needs to combine the ZnS with the dope at very high temperatures for it to work - do you have any ideas re the process? Do I heat the substances together in a crucible? Can it be done over a bunsen burner or do I need a furnace?

[Cforchemistry]

I am not quite sure about the industrial process, but simply mix it may provide sufficient activation. I don't know whether heating make any better.

[sushicraver975]

Fantastic!

[CarnalDiafragma]

What does Dysprosium nitrate do? Glows too right?

[Cforchemistry]

Itself do not glow, It act as doper to help glow powder glows

[Madarpok]

Is it hard to prepare the Cu doped ZnS? Would ZnS by itself glow?

[Cforchemistry]

ZnS itself con glow, but doped one glow better. I will make tutorial on that later on.

[Madarpok]

Thank you.

[genshouthedeliverer]

Interesting. I'll have to give this one a try.

[ironmaidenhans]

Wheres the hposphor pouder. You used

some zinc sulfide I think this is experiment is

not so dangerous when you use zink sulfide

[Cforchemistry]

This experiment is actually not dangerous at all, that is only a disclaimer after one of my video being flagged. Those demostration isn't danger if do properly, but I don't know why it is deleted : (

[daboom2006]

Hi, this channel is quite interesting.

Where abouts are you from?

[weldmaster80]

another chem you can make yourself in your home lab is siply use crushed oster shell and sulfer bother can be gotten at a good garden store mix them together and heat till it all gets black and nasty, than crush and heat once more, best to do all this outside as the sulferdioxide should NOT beinhaled (thin jonny was a chemest but jonny is no more......) anyway this is a week Phosphorescence but IT DOSE WORK, and if you aska good gardener friend you can probably eve do it for free.

[Kuwaiti55]

AMAZING!

5*****

:)

[kingkongtiger]

Thx its really interesting

[Jonathanpoll]

how many colours can you do with it?

[Cforchemistry]

Actually quite a lot, as long as I have that kind of powder, I currently have two kind.

[milotickz]

I bet NurdRage would be delighted to use these!

[farhmoha]

I like the way how you made the video, seems so interesting when presented this way.

[marlin187]

Can you make an Infra Red one mate?

[Cforchemistry]

I don't have any Phosphor powder that emits Infrared, I found they usually lie in blue to UV region.

[Cforchemistry]

BTW, the procedure is just the same if you use other powder.

[marlin187]

Thanks a lot mate.This info is most welcome.Please keep up the exelent work and posting such informatives videos.Thanks again .

[Cforchemistry]

I will do my best!

[joouyang]

Very interesting...

[ChemHow2]

Great video, i've been waiting for something like this!

I agree, copper doped zinc sulfide is the most cost effective way to do it.

Definitely 5 stars, I even favorited it!

Keep up the good work!

[GuppyPal]

yeah, we talked about phosphorescence in my P-chem class. cool stuff!

[KMnO4dalla]

Nice vid:) 5* mate

[MastaShortie]

i gotta try this

[Cforchemistry]

You should try this, and try it with different colour!
