The nature of intrinsic emission and the creation of electron-hole trapping centers in irradiated with ultraviolet and X-rays at 15 K and 300 K was investigated in Li2SO4 by methods of spectroscopy. It is shown that in activated Li2 SO4 with an energy of 6 ÷12.4 eV, emission appears in a wide spectral range to excite rare earth ions that are used as UV sources. These same photons create electron-hole trapping centers as well.
