Testing "aqua" strontium aluminate glow pigment.
Added 2020-03-10 04:06:04 +0000 UTCThe aqua version of the strontium aluminate glow in the dark pigment seems to release light much slower than the green stuff. This means it looks a lot dimmer, but glows for much longer.
I've not tested the last bit - since I'm sleeping well at the moment, so haven't woken to look at it in the early hours.

A very interesting property of strontium aluminate is that it is thermoluminescent so if you heat it up a little it also starts to emitt light. It looks really nice if you put a bit on a heatplate. I bought the strontium aluminate from eli and the bluish ones are alot dimmer than the green one. I am also wondering if the lit strontium aluminate really is brighter than the normal one but i didn't buy it

2020-03-10 20:37:54 +0000 UTCThat's why I mentioned the wire, there would be something hidden that refreshed the pigment occasionally. A slow heartbeat kind of effect.
2020-03-10 19:38:54 +0000 UTCIdea: Pendant made of resin/glow pigment with potted UV LED as you described and a coincell with piggybagged 555 timer circuit that pulses the LED every few seconds to refresh the glow. Would probably look really intresting!

2020-03-10 08:56:08 +0000 UTCI've dipped blue LEDs in pigment loaded resin and it actually blocks a lot of the blue light and creates a glowing hotspot around the LED position when the LED is turned off. Maybe a more diffused resin would work better with less pigment.

2020-03-10 05:53:35 +0000 UTCBetween this and the earlier pendant test ... I keep thinking the pendant version, if you put a small LED into the vial, potted it in place with this kind of glowing resin, and threaded a small wire up the sides of the chain on the pendant top, you might end up with a unique piece of jewelry. I've just nudged the wife to consider something like this.
