摘要：

Visible photoluminescence properties of praseodymium ions in rare-earth aluminum phosphate 5.8Li2O-3CaO-5BaO-16Al2O3 - 4.2La2O3-66P2O5 (LCBALP) glass were investigated and the absolute fluorescence spectra were measured and calibrated in an integrating sphere. The spontaneous emission probability and the maximum stimulated emission cross-section corresponding to the 1D2→3H4 transition are 926.5 s-1 and 3.5×10-21 cm2, respectively. Under the blue LED excitation, the radiant flux and the luminous flux for the visible emission bands of LCBALP glass are identified to be 112.6 μW and 29.7 mlm, respectively. The total quantum yield for the visible fluorescence is determined to be 4.1%. The spectral evaluations of praseodymium ions in optical glass provide a reliable reference in developing optoelectronic devices and compact lighting sources.
