There is a form of phosphorus ("white phosphorus") that emits a faint glow when exposed to oxygen because of a chemical reaction taking place on its surface. So, the answer is "yes, phosphorus does glow in the dark" but only certain types of phosphorus, and only if the darkened room its in has oxygen in it. =)
The measure of the shininess of a rock is called luster. Luster describes how light is reflected off the surface of a mineral or rock. It can be described as metallic, glassy, pearly, dull, or earthy.

Mineral
An accessory mineral is a mineral present in small amounts in a rock, but not considered to be characteristic of the rock.
Jupiter does not produce light. It does, however, reflect a lot of the sunlight that reaches it's surface. The amount of light that a planet's surface reflects is call it's albedo, and it's expressed as a value between 0 (nothing reflected) to 1 (100% of light is reflected). Jupiter has an albedo of 0.34, which may seem small compared to Venus's albedo of 0.9, but since Jupiter has a substantially larger surface area than Venus, what it lacks in reflectiveness it makes up for in size.
luster. Luster refers to how light is reflected off the surface of a mineral or rock, which can help in identifying its characteristics and composition.

luster is how a rock or mineral feflects light on it's physical appearance
Gneiss is a type of rock that has parallel bands of dark and light mineral grains. These bands are a result of the rock being subjected to high temperatures and pressures during its formation, causing the minerals to align in distinct layers.
That's right. But the sun shines on them and lights them up. The same reason you can see a rock in a dark room when you shine a flashlight on it, even though the rock does not produce light.

Mineral
The ability of a mineral to reflect light is known as its luster. Luster is a fundamental property used in mineral identification and classification. Minerals can exhibit various types of luster, such as metallic, vitreous (glassy), pearly, resinous, or dull, depending on their chemical composition and crystal structure. By observing the luster of a mineral, geologists can gather valuable information about its physical and chemical characteristics.
if you mean "luster" then it is the way that a rock or mineral reflects light off of its surface.
the mineral is clay and there is no rock
Luster (or Lustre) is a description of the way light interacts with the surface of a crystal,rock or mineral - For example a metallic lustre or silky lustre.
