Phosphorescent paint is commonly called "glow-in-the-dark" paint. It is made from phosphors such as silver-activated zinc sulfide or doped strontium aluminate, and typically glows a pale green to greenish-blue color. The mechanism for producing light is similar to that of fluorescent paint, but the emission of visible light persists long after ...
Stars made of glow-in-the-dark plastic are placed on walls, ceilings, or hanging from strings make a room look like the night sky. [29] Other objects like figurines, cups, posters, [30] lamp fixtures, toys [31] and bracelet beads may also glow.

DuPont created a number of essentially glow-in-the-dark fillers, finally settling on the non-toxic PB-155 compound. PB-155 (also known as TIARA 5) glows when it oxidizes and therefore could be used to mark things at night with minimal fuss. Developed specifically for the US Navy SEALs, the first production models were created in 1963.
The development of strontium aluminate pigments in 1993 was spurred on by the need to find a substitute for glow-in-the-dark materials with high luminance and long phosphorescence, especially those that used promethium. This led to the discovery by Yasumitsu Aoki (Nemoto & Co.) of materials with luminance approximately 10 times greater than ...
The weapon should be properly balanced in terms of weight. Cheaper or gimmicky nunchaku (such as glow-in-the-dark versions) are often not properly balanced, which prevents the performer from performing the more advanced and flashier "low-grip" moves, such as overhand twirls.
First, it will be useful to introduce some mineralogical terminology for gemstones that can glow when exposed to light, friction, or heat. Note that the following discussion will omit modern techniques such as X-rays and ultraviolet light that are too recent to have influenced folklore about luminous gems.
