title: Specific features of Tm3+ doped BiB3O6 glasses fluorescence spectra and their kinetics.
abstract: Synthesis and spectral fluorescent features of the thulium-doped BiB(3)O(6) glasses are presented. All spectra were recorded using a pulsed (pulse energy ca. 1μJ, pulse duration 10ns) 355nm third harmonic of 10kHz Nd:YAG laser as an excitation source. A laser beam was focused in a backscattering geometry onto about 1mm(2) spot on the surface of a sample. The Andor SR-303i spectrograph equipped with an Andor DH-501 intensified charge coupled device with spectral resolution up to 1nm was used as a spectra recorder. The time-resolution of this system can be as low as 5ns. The decay kinetics was derived from integrated time-resolved spectra. Additionally the absorption and excitation spectra were measured. The main parameters of the Judd-Ofelt analysis were calculated and comparison of the obtained results with corresponding data for other materials was carried out.
