"Fluoresces" Natural Recordings by Native Speakers
To emit light, especially of a bright, glowing color, typically when exposed to ultraviolet light or other radiation.
Fluoresce means to emit light when exposed to radiation, such as ultraviolet light, and then continue to give off light for a period of time after the radiation source is removed. It is often used to describe certain compounds or substances that exhibit this property, such as fluorescent dyes or pigments.
Fluorescein is a yellow-green dye that is used to highlight the tear film and corneal epithelium in the eye. It is commonly used in diagnostic procedures such as fluorescein angiography, which helps to diagnose and monitor eye conditions such as diabetic retinopathy and age-related macular degeneration.
Fluorescence is the emission of light by a substance that has absorbed light or other forms of electromagnetic radiation. This phenomenon occurs when a molecule or an atom returns to its ground state after being excited by energy from a higher energy state. As a result, it releases excess energy in the form of photons, which we perceive as light. Fluorescence is commonly observed in biological systems, such as in the green glow of fluorescent proteins used in microscopy, as well as in materials like neon signs and glow sticks.
Emitting or producing light that is fluorescently bright or glowing, typically in a bright, vivid, or electric blue color.
To fluoridate means to treat or mix with fluoride, a chemical that helps prevent tooth decay and strengthen tooth enamel, often by adding it to water supplies, toothpaste, or mouthwash.
Fluoridated refers to a substance, liquid, or toothpaste that contains the chemical fluorine in the form of fluoride ions. This is typically done to prevent tooth decay and promote good oral health.
Fluoride is a naturally occurring compound that is found in water, soil, and many types of foods. It is a key nutrient that is important for oral health, as it helps to prevent tooth decay and strengthen tooth enamel. Fluoride can be added to toothpaste, mouthwash, and community water supplies to help prevent tooth decay and promote good oral health.
