Abstract: The paper presents the results of studies of photoluminescence (PL) of glass at a temperature of 12.6 K under the influence of synchrotron radiation λexc = 45 nm. It was found that the obtained PL spectra consist of three bands $λ_{mon}$ = 278, 336, and 379 nm. Studies of the excitation spectra by scanning with the registration of luminescent radiation at λmon = 280, 330, and 390 nm revealed four bands for each $λ_{mon}$. It is proposed that the main band at 278 nm in the excitation spectra is associated with centers based on Ag$^+$ ions that occupy the Li$^+$ sites in the glass structure, while the other two bands at 336 and 379 nm are associated with centers based on Ag$^{+}_2$ and Ag$^{+}_3$ conglomerates. B$3^+$ – O$^–$ centers based on structural defects in boron oxide complexes may be responsible for the weak 110 nm excitation band.
