The methods of vacuum ultraviolet and thermal activation spectroscopy were used to measure the excitation spectra of impurity radiation in the fundamental absorption band of K2SO4-Cu crystals at 15 K and 300 K. An energy transfer was detected from the base to Cu+ impurities. The band gap of crystals K2SO4 was estimated. In K2SO4-Cu crystals, recombination radiation bands were detected at 2.95 รท 3.0 eV corresponding to electron hole capture centers.
