Incandescence is the emission of light due to high temperature, such as in a traditional light bulb, while luminescence is the emission of light without heat, like in glow-in-the-dark materials. Incandescence is less energy efficient because it produces more heat than light, while luminescence is more energy efficient as it produces light without generating excess heat.
Fluorescence is a type of luminescence that occurs when a substance absorbs light at one wavelength and emits light at a different wavelength almost instantaneously. Luminescence, on the other hand, is a broader term that refers to the emission of light from a substance without the need for high temperatures.
Luminescence is a physical property that involves the emission of light from a material when it is exposed to certain stimuli, such as electricity or radiation. It is not a result of a chemical reaction, but rather a characteristic of the material's structure and properties.
There are a few causes of luminescence, but one of the major causes is bioluminescent bacteria. They can be found independently or in a symbiotic relationship with organisms around the world. The other types are luminescence is chemiluminescence, electroluminescence, electrochemiluminescense, photoluminescense, thermoluminescence, and thermoluminescense.
Luminescence is the emission of light from a material due to various processes such as electron transitions, molecular vibrations, or chemical reactions. It can be caused by the recombination of excited electrons with holes in a semiconductor material, by the relaxation of excited molecules to lower energy states, or by the release of energy during a chemical reaction.
the state of glowing while at a high temperature, caused by electrons in vibration atoms and molecules that are shaken in and out of their stable energy levels, emitting radiant energy in the process. The peak frequency of radiant energy is proportional to the absolute temperature of a heated substance
The noun luminescence means the emission of light at low temperatures by any process other than incandescence.
Illuminance is another word for 'luminous-flux density', which describes the intensity of the luminous flux hitting a surface. Its SI unit of measurement is the lux, which is a special name given to a lumen per square metre. Luminance is a measure of the intensity of the light reflected by a surface. Its SI unit of measurement is the candela per square metre.

The emission of light that does not derive energy from the temperature of the emitting body
Fireworks emit light through three processes: incandescence, luminescence, and incandescence. Incandescence is the glowing of heated particles, luminescence is the emission of light without heat, and chemiluminescence is the light emitted from a chemical reaction.
Luminescence is the emission of light from a substance not caused by heat. It can be generated through various processes such as fluorescence, phosphorescence, chemiluminescence, or bioluminescence. These processes involve the absorption of energy and subsequent re-emission of light by the substance.
Correct, an electric bell does not exhibit incandescence. Incandescence is the emission of light due to high temperature, typically seen in incandescent light bulbs. Electric bells operate using an electromagnet to produce sound, not light.

The form of energy that refers to luminescence is electromagnetic energy. Luminescence is the emission of light from a material when energy is supplied to it, often in the form of electromagnetic radiation. This can include visible light as well as other forms of electromagnetic radiation such as ultraviolet or infrared.

Inflorescence is a botanical term that describes a cluster of flowers on a plant, which is contrasted with single flowers that do not occur in bunches. You can kind of see the root "flor" give away the reference to flowers. Florescence is a word that describes a period of flourishing, but it is merely one letter away from a far more commonly used word, "fluorescence". Fluorescence is defined as the emission of electromagnetic radiation by a substance that is stimulated by incident radiation. That's a very broad definition, but the term is often used to apply to minerals that glow any color in the visible spectrum when exposed to invisible ultraviolet radiation. Fluorescence is distinct from incandescence and luminescence. Influorescence generally describes the emission of visible light, it can also apply to the emission of wavelengths that are invisible; however it also stipulates such emissions are spurred by the absorption of electromagnetic radiation. Incandescence and luminescence both are defined as emitting visible light only, with the former being induced by the application of heat, and the latter being induced by non-thermal means (such as chemical reactions). With all of this said, it's worth pointing out that "influorescence" is not a word.
A phosphor activator is a chemical substance added to a phosphor material to enhance its luminescent properties. It works by promoting the efficiency of the energy transfer process within the phosphor material, leading to brighter and more long-lasting light emission.
