Shadow
I don't know if I have misunderstood this question, but dark is the absence of light. The only darkness that I can think of which is made by light are shadows, when light rays are blocked by an opaque object.
A shadow is made of light, as it is created when light is blocked by an object, causing darkness where the light cannot reach.
In short, nothing. A shadow is a dark area within a brighter area. It doesn´t have any substance as it is just a place where light is not falling as its being blocked by somthing. A shadow can be thought of as an opposite to a rainbow which is made by light shining on a specific place. Both have no substance but seem to be solid and can appear to move.
A shadow is a dark area created when an object blocks light from reaching a surface. Shadows are formed when an object obstructs the path of light, causing a shadow to appear on the opposite side of the light source.

Glow-in-the-dark silicone bracelets are made with phosphorescent materials that absorb and store light energy when exposed to light. When in the dark, they slowly release this stored light energy in the form of a dim glow. The process is called phosphorescence.
