In an article on the New Scientist website there was some interesting information about making plants give off light.  It reads...

 

Gold brings colour to water plants

Can a living thing give off light without being bioluminescent? It can - if it's full of gold nanoparticles.

A team headed by Yen Hsun Su of the Research Center for Applied Sciences at the Academia Sinica in Taipei, Taiwan, dipped Bacopa caroliniana, a plant often used in aquaria, into a solution of gold nanoparticles. The gold diffused into the plant's cells after a day or so. When the plant was exposed to ultraviolet light, it excited electrons in the gold, causing them to emit a violet-blue light. That light in turn made the plant's chlorophyll fluoresce red.

The nanoparticles remained in the leaves for between two weeks and two months.

 

In my other post titled "Someday you will glow with light!", I postulated that Adam and Eve may have put on fig leaves because they still emitted light even after Adam and Eve had lost their light.  This article makes that seem plausible.
