Glow in the dark beads
Hello all,
Please examine the attached image of a bead. The left side shows the bead under ambient room lighting, while the right side captures it in a dark
environment after UV exposure, demonstrating its photoluminescent properties. As observed, the bead emits visible light in darkness following UV
excitation.
I have a few technical inquiries regarding this material:
1- Does anyone have insights into the specific photoluminescent compound or class of chemicals likely responsible for the light-emitting properties of
this bead?
2- The bead material appears to resemble a thermoset polymer. but the link here: https://www.amazon.com/Misright-Necklace-Decoration-Birthday... says it is acrylic!
3- Would it be feasible to dissolve or chemically modify this bead material and subsequently reform it into a new shape using a mold? If so, any
guidance on potential solvents or processes would be appreciated.

The photoluminescence compound is probably strontium aluminate, or possibly zinc sulfide. If it is acrylic, it should dissolve in DCM.

Back in the day I bought phosphorescent powder from fishing supply stores. This can be added to clear epoxy or whatever castable polymer you prefer,
there are many to choose from. I used it on boomerangs for nighttime throwing.
We're not banging rocks together here. We know how to put a man back together.

Hi Fulmen, and thank you for your reply.
Do you happen to know what type of powder this might be? As far as I remember, I have not encountered such phosphorescent powder in any local fishing
supply stores. I do have some phosphorescent acrylic paints, manufactured in China, though they appear to be of lower quality compared to the bead I
shared. Specifically, the paints do not glow as brightly, and their light-emitting properties fade significantly faster.

Hi Sir_Gawain, And thanks for your reply.
By DCM you mean Dichloromethane (Methylene Chloride) right?

No sorry, I have no data on it. IIRC I found it in the ice fishing supplies.

After doing more research on YouTube, I think Strontium Aluminate compound and its variants will show lower rates of fading.
