Laser ablated silver nanoparticles doped blue light-emitting polymer optical fiber with enhanced photostability

Here, we demonstrate the fabrication of a stable polymer optical fibre doped with 1,4-bis (2-methylstyryl) benzene (Bis-MSB) that contains silver nanoparticles. Spherical nanoparticles approximate size 15 nm were fabricated using nanosecond laser ablation. A Q-switched Nd: YAG operating at 355 was used to pump fiber in order analyse its emission characteristics. The pulse energy (PPE) dependent spectra from analyzed. observed fluorescence turned amplified spontaneous (ASE) PPE 2.5 mJ. study demonstrates offers superior photostability an optimum concentration Ag proposed may find potential applications development directional sources blue region.
