A phenomenon that causes certain materials to glow (without getting hot) when electrically excited.

No it doesn't. It occurs through electroluminescence. Luminescence is light that occurs without heat. Elecroluminescence occurs when electrons in the neon gas get excited by the electricity thus producing light.
The glow of neon light is caused by electrons emitting energy as they transition between different energy levels within the neon gas atoms. When an electric current passes through the gas, it ionizes the neon atoms, exciting the electrons. As these excited electrons return to their lower energy states, they release energy in the form of light, producing the characteristic bright glow of neon signs. This process is known as electroluminescence.
Common sources of light, such as the sun, incandescent bulbs, and LEDs, produce light through different mechanisms. The sun generates light through nuclear fusion, where hydrogen atoms fuse to form helium, releasing energy in the form of light and heat. Incandescent bulbs produce light by heating a filament until it glows, while LEDs (light-emitting diodes) emit light through electroluminescence, where electrons recombine with holes in a semiconductor material, releasing energy in the form of photons. Each source utilizes distinct processes to convert energy into visible light.
LEDs can also be designed to emit light in the infrared spectrum, but the radiation emitted is very slight and only has limited use, such as communication between electronic devices using infrared ports and signals. Since the diodes are so small, they cannot easily be used to generate large amounts of heat. Other LEDs fall in the visible light spectrum, with some nearing ultraviolet light.

Typically when you are either nervous or amused.
As depth increases temperature drops, water pressure increases and the eyes of sea creatures become more primitive. Electroluminescence plays a greater part in identification.
the 3 other ones are bioluminescence, phosphorescence and electroluminescence
Bioluminescence, chemiluminescence, crystalloluminescence, electroluminescence, photoluminesce and mechanoluminescence are all different types of luminescence. The terms are about different luminescence provenience, in the above other, biological, chemical, crystal, electrical, photo and mechanical.
Electrical energy is converted to light energy through a process called electroluminescence, where the energy from electrons flowing through a material is released as light. This conversion occurs in devices like light bulbs, LEDs, and fluorescent lamps.
Electrical energy is converted into light through a process called electroluminescence. This occurs when an electric current passes through a material, causing it to emit light. This phenomenon is commonly used in light bulbs, LED lights, and other lighting technologies.
Electricity is converted into light through a process called electroluminescence. When an electric current passes through a material, it causes the atoms to release energy in the form of photons, which are then emitted as light. This principle is used in various lighting technologies such as incandescent, fluorescent, and LED bulbs.
That varies, depending on the technology. In an incandescent light bulb, a wire is heated when electricity passes through it, until it glows. In a fluorescent light bulb, atoms in a gas get into an excited state, and emit light when the electrons fall back to their normal energy level.
Electric lights work by passing an electric current through a filament or gas inside the bulb. The current causes the filament to heat up and emit light, or the gas to produce light through a process called electroluminescence. The light is then emitted out of the bulb through a transparent covering.
LEDs (light-emitting diodes) produce light through a process called electroluminescence. When a voltage is applied to the diode, electrons and electron holes combine in the semiconductor material, releasing energy in the form of photons (light). The specific material used in the LED determines the color of the light produced.
LEDs produce color through a process called electroluminescence. When an electric current passes through the semiconductor material in an LED, it excites the electrons within the material, causing them to release energy in the form of photons. The color of the light produced depends on the specific materials used in the semiconductor layers of the LED.
