Examples

  • Two years ago, two research collaborations reported photoluminescence characteristic of exciton emission that occurred in a circle some distance from where a laser had initially formed excitons.

  • Also, while photoluminescence is an incoherent process, light scattering is fundamentally coherent.

  • The degradation in the minority carrier lifetimes under these laser-processed regions was studied using the photoluminescence (PL) imaging technique.

    Academic text (2018)
  • Using a dynamic photoluminescence (PL) imaging method proposed by Ramspeck et al., we were able to generate a spatially resolved minority lifetime mapping of our samples.

  • In the laboratory, the team measured the photoluminescence of the material after exposing it to light.

  • The researchers observed that the photoluminescence increased when the substance was heated.

Light that a material gives off without heat

is limited to emission after photons are absorbed and often used in laboratory contexts

Surface Forms

Morphology

photoluminescence = luminescence (semi-transparent) = photo + lumin + escence

The target is formed by adding the scientific prefix photo- to luminescence, but the term remains specialized and not fully predictable for many learners.

Etymology

Photoluminescence comes from photo- which means 'light', as in photograph, and from luminescence based on lumen, which also means 'light' and appears in luminous. It describes a material that 'glows' after it absorbs light, so the word literally says 'light shining from light'.
