摘要

•High optical quality and chemical purity glass with the Li2B4O7:Cu,Eu composition is obtained.•XRD, EPR, UV–Vis absorption, and photoluminescence of the Li2B4O7:Cu,Eu glass are studied.•Spin Hamiltonian parameters of Cu2+ ions in Li2B4O7:Cu,Eu glass are calculated and analysed.•Optical band gap (Egopt) and Urbach energy (ΔE) for obtained glass are evaluated and analysed.•Luminescence spectra and decay kinetics of Eu3+ and Cu+ ions in studied glass are interpreted.
