摘要：

Rhodamine B (Rh-B) has been embedded in PolyAcrylic acid (PAA) films. The materials are studied for the laser action with nitrogen laser excitation. The lasing efficiency of Rh-B/PAA films is comparable to that of rhodamine 6G in methanol. There is a 50% reduction in the laser intensity of the films with 2600 pulses from the N-2 laser (2 Hz). The photostability of these materials is far superior to that of other polymeric materials and is comparable to that of sol-gel materials.
