How Do You Spell PHOTOLUMINESCENCE?

Pronunciation: [fˌə͡ʊtə͡ʊlˌuːmɪnˈɛsəns] (IPA)

Photoluminescence is spelled with four syllables and can be broken down phonetically as /ˌfəʊtəʊluːmɪˈnɛsns/. The first syllable "photo" is pronounced with a long "o" sound like "foe" and the second syllable "lumu" is pronounced with a short "u" sound like "lum" before the stress falls on the third syllable "mi". The fourth syllable "nescence" is pronounced with a short "e" sound followed by a nasal consonant "-ns". Photoluminescence refers to a type of luminescence that is caused by the absorption of photons.

PHOTOLUMINESCENCE Meaning and Definition

1. Photoluminescence is a physical phenomenon that involves the emission of light from a substance after it absorbs photons or electromagnetic radiation. This process occurs when the absorbed energy excites the electrons within the material, causing them to transition to a higher energy state. Once in this excited state, the electrons quickly return to their ground state, releasing the excess energy in the form of light. The emitted light can have a variety of wavelengths and colors, depending on the energy levels involved in the transition.

   The photoluminescence phenomenon is widely studied and utilized in various fields such as materials science, chemistry, and optoelectronics. It plays a crucial role in the development and characterization of luminescent materials and devices. By studying the emitted light, scientists can gain valuable insights into the electronic properties, energy levels, and structure of the materials.

   Photoluminescence is often categorized into two major types: fluorescence and phosphorescence. Fluorescence refers to the immediate emission of light upon exposure to energy, while phosphorescence involves the delayed emission of light after energy absorption. Both types have distinct characteristics and are used in different applications ranging from sensor technologies and lighting to medical imaging and display technologies.

   Overall, photoluminescence is a fundamental process that describes the emission of light from a substance as a result of energy absorption, making it a crucial concept in the field of optoelectronics and luminescence research.

Etymology of PHOTOLUMINESCENCE

The word "photoluminescence" has a Greek etymology.

The word derives from two Greek roots:

1. "photo-" (φωτός) meaning "light".

2. "-luminescence" (-λύμενος) meaning "to emit light".

Therefore, when combined, "photoluminescence" refers to the emission of light after the absorption of photons.
