Electron hole capture centers in an irradiated K2SO4-Cu crystal

Abstract

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 ÷ 3.0 eV corresponding to electron hole capture centers.
