RADIOPHOTOLUMINESCENCE IN THE TISSUE-EQUIVALENT LiB<sub>3</sub>O<sub>5</sub>:Ag GLASSES
The absorption, photoluminescence (PL), and radiophotoluminescence (RPL) spectra in lithium triborate glass (LiB3O5:Ag), doped with 1% silver ions and irradiated with different doses of -radiation in the 0-20 Gy range have been investigated.The change of these spectra as a function of irradiation dose was also measured.The PL spectra of Ag + are dominated by an ultraviolet broadband at about 290 nm.The RPL band is centered at about 430 nm at the excitations in the 310-350 nm spectral region.The mechanism of RPL emission arises from a change in the charge state of silver to A 0 -type centers when Ag + -doped glass is exposed to radiation that generates electrons and holes.
