June 12, 2023 - Scintillator | What are Scintillator Materials?

Scintillators, luminescent materials that emit light when exposed to ionizing radiation, have revolutionized the field of radiation detection and imaging. From homeland security to medical diagnostics, scintillators play a vital role in a wide range of applications. In this blog post, we will delve into the fascinating world of scintillators, exploring their properties, applications, and significance in various industries.

Properties and Mechanism:

Scintillators possess the unique property of luminescence, which allows them to absorb energy from incoming particles and re-emit it in the form of light. When struck by ionizing radiation, scintillators absorb the energy and enter an excited state. The subsequent relaxation process can lead to two phenomena: delayed fluorescence or phosphorescence, depending on the type of transition and wavelength of the emitted optical photon.

Applications:

  1. Homeland Security: Scintillators are extensively used by the American government as radiation detectors for homeland security purposes. These detectors help in identifying and preventing the illicit transportation of radioactive materials.
