Autoluminescence is a fascinating concept that has been studied and researched by scientists for many years. It is a phenomenon where a substance emits light without any external stimulation or source of energy. In this article, we will explore the definition, origin, meaning, associations, synonyms, and antonyms of autoluminescence.
Definitions
Autoluminescence is a phenomenon where a substance emits light without any external source of energy. It is a type of luminescence that occurs due to the chemical or physical properties of the substance. The light emitted by the substance can be of different colors and intensities.
Origin
The origin of autoluminescence can be traced back to the early 20th century when scientists first observed the phenomenon in certain materials. The term “autoluminescence” was coined by the French physicist Paul Langevin in 1921. Since then, autoluminescence has been studied extensively in various fields of science, including chemistry, physics, and biology.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, autoluminescence is defined as “the spontaneous emission of light by a substance without any external stimulation.” The Oxford English Dictionary defines it as “the emission of light by a substance without any external source of energy.”
Associations
Autoluminescence is associated with various scientific fields, including materials science, chemistry, physics, and biology. It is a phenomenon that occurs in certain materials and can be used for various applications, such as in luminescent paints, glow-in-the-dark toys, and medical imaging.
Synonyms
Some synonyms of autoluminescence include self-luminescence, self-illumination, and self-glow.
Antonyms
There are no specific antonyms of autoluminescence, but it can be contrasted with other types of luminescence that require an external source of energy, such as fluorescence and phosphorescence.
