Triboluminescence – Batteries, Glow Paint and Fire

Jeri Ellsworth’s attempt at making electroluminescent phosphor, yields crystals that emit light when crushed. Smash-Glow Crystals or Triboluminescence.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. FYI, sugar is triboluminescent too. Take some large sugar crystals, turn out the lights, and smash with a hammer. You should see some very faint purple light. Wintogreen lifesavers have an even more dramatic effect.

  2. I vaguely recall an old “chemistry experiment” book that claimed you could produce glow-in-the-dark paint by roasting together sulfur and Oyster Shells (Calcium Carbonate.) Apparently whatever doping ingredient was needed was already present in the oyster shells…
