Overview

Demonstrates enhanced photoluminescence in SrF2:Sm3+ nanocrystals after X-ray exposure, suggesting their use as X-ray storage phosphors.

Key Points

  • The research aims to investigate the photoluminescent properties of SrF2:Sm3+ nanocrystals after X-ray treatment.
  • Synthesized nanocrystals using a co-precipitation method.
  • Analyzed photoluminescent emissions before and after X-ray irradiation.
  • Monitored changes in emission intensities with varying X-ray doses (0–300 Gy).
  • Examined the kinetics of Sm3+ reduction to Sm2+.
  • Non-irradiated samples showed characteristic emissions from Sm3+.
  • X-ray irradiation resulted in intense emissions from Sm2+.
  • Photoluminescence intensity evolution followed first-order kinetics.
  • SrF2:Sm3+ exhibited faster Sm3+ reduction compared to CaF2:Sm3+.
