X-ray to Microwave fluorescence

Click For Summary
SUMMARY

The discussion centers on the feasibility of using specific elements to absorb X-rays and emit radiation in the microwave band, rather than thermal radiation or fluorescence. Participants highlight that microwaves, with energies around 0.4meV, are likely too low for effective fluorescence. Most scintillators are designed to operate within the visible to UV range due to their bandgap sizes. For a comprehensive understanding of fluorescence mechanisms, a relevant resource is provided.

PREREQUISITES
  • Understanding of X-ray absorption principles
  • Knowledge of fluorescence and scintillation mechanisms
  • Familiarity with bandgap energy concepts
  • Basic principles of electromagnetic radiation
NEXT STEPS
  • Research the properties of scintillators and their bandgap energies
  • Explore the relationship between X-ray energies and fluorescence emissions
  • Investigate materials that may exhibit microwave fluorescence
  • Study the mechanisms of fluorescence in various materials
USEFUL FOR

Researchers in materials science, physicists studying radiation interactions, and professionals in the field of scintillation and fluorescence applications.

Hello,

Is there any specific element that would absorb x-ray and emit radiation roughly in microwave band (not thermal radiation, fluorescence). Or could it be achieved by mixtures and gradual wavelength increase?

Thank you.

Microwaves are probably way too low in energy. 100 GHz ~ 3 mm ~ 0.4meV. Loosely, the energy of flourescence is given by the band gap in the scintillating material.

Most scintillators operate in the visible to UV range, because that's about the size of the bandgaps.
