I'm assuming you don't mean such things as incandescent bulbs, Cathode Tube displays, and LED displays.
Phosphorescence is the name given to natural materials that glow without external stimulus.
At one end of the range, we have the fireflies and glow-worms, and many other biota that produce light as part of their mating or food catching behaviour. The phosphorescence of minute sea creatures all glowing in the wake of a ship is a commonly marvelled sight.
Some decay products glow quite naturally in the dark, though there is no further purpose behind the glow. (For they are non sentient). In New Zealand, a green fungal decay of beech wood is a common glow in the night time forest. A NZ worm displays phosphorescence in its fluids - but this may be due to consumed material.
And of course it is named phosphorescence because some types of Phosphorus glow by themselves. Well, actually white phosphorous will slowly oxidize in the air, and strictly, this is chemiluminescence.
Radioactivity was first identified in 1896 by Becquerel when he was studying substances that glowed naturally in the dark.

What type of object can be seen in darkness and why?
luminous objects allows to absorb ans emits light.
What determines the kind of wavelength and the amount of radiation that an object emits?
just had this on a test, the answer is Temperature
Why is solar energy transfered to earth by radiation?
That is because every object emits electromagnetic radiation, according to its temperature.That is because every object emits electromagnetic radiation, according to its temperature.That is because every object emits electromagnetic radiation, according to its temperature.That is because every object emits electromagnetic radiation, according to its temperature.
An hot object emits less radiation than a cool object emits?
Generally, yes. For example, a hot coil may emit infrared or even red light, and hot iron glows. When cool, however, they do not emit light. The reason is that electrons are given more energy from the heat, so they raise in their location from the atom, and when they return to a stable location they give off light.
What object emits infra-red?
all object that are warmer than absolute zero but not warm enough to glow emits some amount of infra red.
If an object emits or reflects light?
It can be seen by the eye.
What object is made black so that it emits heat?
coal is made black so that it emits light
What kind of object swallows everything and emits radiation?
This question is a contradiction.
Why is the statement the color of an object depends on the wavelengths of light it absords inaccurate?
...because the colour of an object depends on the wavelength of light it reflects, or the wavelength of light it emits.
Why do object appear white?
A white object emits light in all/most of the visible spectrum evenly.Because it reflects all the light back.
Is gold non luminous object?
sun (a luminous object) emits its own light and the moon ( a non luminous object ) reflects the light from the sun to earth that's how we can see the moon. The same way gold is a non luminous object.
What are two ways that an object gives of light?
A torch emits light from the bulb. A mirror gives off light by reflection.
Is a burning candle luminous?
A candle is a luminous object because it emits to light by itself
What does a star emits?
The spectrum is a kind of analysis of the light emitted by a star.
Are you able to see an object when it emits or reflects one or more visible light frequencies?
Yes.
What type of object can be seen in darkness and why?
luminous objects allows to absorb ans emits light.
Does not emit light?
The sun is the only object in the solar system that generates and emits visible light. Any of the others is a correct answer to this question.
