Sulfur and Tin did not mix ... (trying to make DIY phosphor)

Hi ...

Here is an other "failed experiment" ...

I tried to mix Sulfur and Tin with the hope to make a ZnS phosphor ... (Yes, I know ... I confused Sn and Zn)

So, indeed, when I poured some Sulfur powder over my melting Tin, the Sulfur melted, boiled and vaporized ...

Ok. Now my question :
If I pour some Sulfur powder over melting Zinc, will Sulfur vaporize, or will I get some ZnS ?
(actual question : is there a simple non industrial mean to make ZnS phosphor ?)

Sorry, this method may be stupid, but did you ever tried to mix zinc powder with sulfuric acid ?

maybe it's work

Sulfur powder and Tin can not made ZnS,

ZnS, Insoluble in water, soluble in acid. See the sun dark discoloration. Long home moist air into zinc sulfate. Generally the role of hydrogen sulfide and zinc salt solution obtained. If the crystal ZnS adding trace amounts of Cu, Mn, Ag activator done by light, the sounds of different colors of fluorescence. Reagents used for analysis, coatings, manufacturing paints, white and opaque glass, filled rubber, plastics, and for the preparation of phosphors. The sulfur obtained by heating with zinc. so your Method can't successful!

I'd be tempted to mix powdered tin and sulphur and then light it. A similar mixture of zinc and sulphur is a form of solid rocket fuel.

Ah yes ! This remind me an experiment when I was at school ... Sulfur powder + a metal powder (aluminium ?) was lightened with a Bunsen torch, and the powder mix burned slowly in an exothermic reaction, giving a strange solid substance as result ...

Should I be prepared for an explosive reaction ?... =o/

Anyway, as I don't have zinc, this will postpone this experimentation ...

Zinc Sulfide (ZnS) seems to be the easiest phosphor I could make ...

ZnS:Cu = greenish
ZnS:Ag = bluish
(Strangely, the red or white are not that easy to obtain ....)
Could it have been iron filings? It's a standard practical in UK schools - a mixtures of sulphur and iron is easily separated, say with a magnet, electrostatic charge or dissolving the sulphur in acetone, but heat the mixture in a test-tube, an exothermic chain-reaction turns the mixture into a lump of non-magnetic, insoluble iron-sulphide (it's a way of demonstrating how combining elements into compounds gives us the wide range of phyical properties of the substances we see).

It's possible ... I don't really remember.
I think it was mainly related to Moles and Avogadro's number.

Thanks for reminding me this "recipe" =o)
I can't wait to find zinc ...
Been reading through this thread and find there is no mention about whether (or not) any of the above mentioned phosphors will luminesce when irradiated with an 2 MeV electron beam. Any ideas?
You can get zinc powder by grinding down the inner metallic casing of a zinc-carbon dry cell battery. Don't confuse this with that black rod in the middle of the cell, though! That's made of carbon. Also, the powdery and slightly moist stuff around the rod is manganese dioxide.

I have a question, when the zinc of the dry cell battery corrodes, it forms some kind of brittle white stuff, what is it?

That is zinc oxide, which is formed when zinc metal combines with oxygen, yielding the white deposits.
