摘要：

Intense blue fluorescence is observed in a Tm3+-doped BIGaZYTZr fluoride glass after single wavelength red or infrared CW pumping. Dynamics and power dependences of both (1)G(4) and D-1(2) fluorescences under 648.7 nm excitation reveal a photon avalanche mechanism in the 3 mol% doped sample. Selective pursed excitation indicate an almost purely radiative relaxation at low concentration in agreement with Judd-Ofelt calculations. At higher concentration, cross-relaxation energy transfer and excited state absorption mechanism compete to feed the (1)G(4) and D-1(2) levels. The concentration, temperature and time dependences of these fluorescences are investigated.
