•UV–VIS absorption, excitation and time-resolved luminescence spectra are done.•The ratio of crystal field strength to Racah parameter indicates a borderline case between strong and weak field.•The sample have some SHG capabilities that can be increased by poling the glass by proton implantation.
Synthesis, spectral properties and photoinduced nonlinear optical effects of chromium-doped BiB3O6 glass are studied in the present paper. Absorption, excitation and time resolved luminescence spectra are presented and luminescence decay behavior is discussed. Detailed analysis of the obtained spectra (assignment of the most prominent spectral features in terms of the corresponding Cr3+ energy levels, crystal field strength Dq, Racah parameters B and C) was performed. A weak photostimulated second harmonic generation signal was found to increase drastically due to poling by proton implantation in the investigated sample.
