Summary
This study introduces a novel method for creating optical fibers doped with YPO4:Pr3+ nanocrystals. This technique preserves the nanocrystals
Area of Science:
- Materials Science
- Optoelectronics
- Nanotechnology
Background:
- Developing novel optical fibers with enhanced luminescent properties is crucial for advanced photonic applications.
- Incorporating rare-earth-doped nanocrystals into optical fibers requires methods that maintain the nanocrystals' optical integrity.
- Previous methods often struggle to preserve the luminescent properties of dopants during fiber fabrication.
Purpose of the Study:
- To present a new glass powder-nanocrystal doping method for fabricating optical fibers.
- To incorporate YPO4:Pr3+ nanocrystals into a P2O5-based glass optical fiber.
- To characterize the optical and luminescent properties of the resulting doped optical fiber.
Main Methods:
- Synthesis of YPO4:Pr3+ nanocrystals (NCs) using co-precipitation and hydrothermal methods, optimized for size (<100 nm) and Pr3+ concentration (0.2 mol%).
- Selection of a non-silica P2O5-containing glass core with a refractive index (n=1.788) matched to the NCs.
- Fabrication of the optical fiber preform via a modified powder-in-tube method after pre-sintering a glass powder-NC mixture, followed by fiber drawing.
Main Results:
- The YPO4:Pr3+ doped optical fiber exhibited luminescent properties consistent with the synthesized NCs, showing sharp Pr3+ emission at 600 nm (1D2-3H4 transition).
- The emission lifetime of the 1D2 level was measured at 156 ± 5 µs under 488 nm excitation, confirming preserved NC properties.
- TEM-EDS and FIB-SEM analysis confirmed the distribution of YPO4:Pr3+ NCs within the core region of the optical fiber.
Conclusions:
- The glass powder-NCs doping method is effective for producing optical fibers with well-preserved nanocrystal luminescent properties.
- The fabricated YPO4:Pr3+ doped optical fiber demonstrates promising characteristics for active photonic device applications, including lasing.
- This work establishes a new pathway for developing advanced active optical fiber materials.
