摘要：

Eu(DBM)(3)Phen-doped poly(methyl methacrylate) (PMMA) with different doping concentrations was prepared. Judd-Ofelt parameters Omega(2) and Omega(4) and the fluorescence intensity ratio R were computed from the fluorescence emission spectra and were analyzed. The radiative properties, such as transition probabilities, emission cross section (46.47 x 10(-22) cm(2)), fluorescence branching ratios (90.34%), and radiative ;lifetime (1.704 ms), reveal that Eu(DBM)(3)Phen-doped PMMA has potential use as a laser material.
