摘要：

Steady-state and time-resolved laser spectroscopy of Pr3+-doped KPb2Cl5 crystal has been investigated for the first time. Visible luminescence from P-3(1) and P-3(0) states under excitation in the P-3(2.1,0) states has been analyzed. The fluorescence decays of states P-3(1) and P-3(0) have been measured at 10, 77, and 295 K. Emission from level D-1(2) is only observed when this level is directly excited. Anti-Stokes emission from levels P-3(1) and P-3(0) following excitation of the D-1(2) state has been observed between 10 and 295 K. The temporal behavior of the upconverted emission indicates that an energy transfer upconversion. is the dominant mechanism for the upconversion process in this crystal.
