Abstract

Praseodymium-doped BiB3O6 glass was synthesized and a wide range of its optical properties was studied, including absorption, excitation and high resolution time resolved luminescence spectra. Particular interest was devoted to study of their time decay kinetics of induced fluorescence under influence of the third harmonic Nd:YAG laser illumination (355nm). Role of borate glass matrices contributing through the electron–phonon interaction to the time-decay kinetics of fluorescence is discussed. Comparison with other glass matrices is performed both following the Judd–Ofelt analysis as well as experimental decay times for principal fluorescence lines.
