摘要: Spatially separated defects created by photons with energies 6–8 eV in alkali-earth fluoride crystals doped cerium are investigated the help of thermoluminescence. Measuring spectra creation Vk and H peaks thermostimulated luminescence inBaF2:Ce3+. we demonstrate that higher than 6eV induce centers (self-trapped holes captured interstitialF ions), whereas formation self-trapped begins on exposure to greater 7 eV. The influence photoionization theCe3+ inBaF2, SrF2, CaF2, andCeF3 is range photon 4–8 An exponentialCe3+-emisson decay was observed for excitation energy lying 4–6 Slow fast components were under 6 We believe slow due tunnel recombination trapped electrons hole centers.
